The Cranium Stadium
Okay! Before we get into this week’s challenge, I must first announce last week’s winner.
Winner from Week #1
No one
No one
Well… umm… it seems like the first of the two challenges from last week was quite the stumper - no one even tried it. I guess I will have to take the blame for that one; my directions were probably not clear enough. No worries, though. There is always the next challenge! But before we get to this week's new problems, let me explain the problems from last week.
Answer to Question #1 (from Week #1)
For the first question, you had to find a hidden message in the following:
Well the answer was: “Drink your ovaltine.”
How do you get that answer? Well, starting with the first letter of the original (which is a “d”), write down every 5th letter.
Answer to Question #2 (from Week #1)
The second problem reflected everyone’s high school nemesis: a story problem. Here it was:
“Mike is able to run at a pace of 300,000 cm in 3600 seconds. Dave is able to travel 0.6 km in 2 minutes and 37 seconds. If these two guys were to race for a distance of 1,300,000,000 nm, which would win? How long would it take the winner (in seconds)?”
To solve this, you are going to need to convert all of those different sorts of length measurements into the same unit (you can choose any unit, but I will convert all to meters) and all the time measurements into the same unit (seconds is easiest). Okay, so when you do that you get:
“Mike is able to run at a pace of 3,000 m in 3600 seconds. Dave is able to travel 600 m in 157 seconds. If these two guys were to race for a distance of 1.3 m, which would win? How long would it take the winner (in seconds)?”
Easy, right? :) Now you can figure out their speeds in m/s. To do that, you just divide the distance by time. So, Mike’s speed is 0.83 m/s, and Dave’s speed is 3.82 m/s. Just knowing the speed, you can tell that Dave would win because he travels faster.
But how long would it take him to win? Just divide the distance traveled (1.3 m) by the speed (3.82 m/s) to get 0.34 s.
This was the easier problem of the week as 3 people were able to get it correct. These people were @hungry-nomad, @cyoadventuregame, and @macro-d. For getting one of the two questions right, you got my upvote.
Without further ado, let’s move onto this week’s challenges!

This Week's Problems
#1 - Find the Hidden Message
Well, now that you know how to do these problems better, let’s give it another go! Find the hidden message in the quoted text:
#2 - Solve the Problem
Jack is rowing across a river. The river flows from the east at 233 cm/s. Jack points his canoe directly north and rows his canoe across the river at 4.8 km an hour. If the river is 2400 m wide, how long does it take Jack to cross the river, and how far away from his original position will he be when he reaches the other side?
Have fun and do your best!
You got the first one completely correct, and the second one partly correct. Just one step away from the correct answer! Check out this week's announcement post for the answer. Find it here.
May the force be with you.
It takes Jack 30min to cross. He ends up 4194m to the east as well, so 4832.146m from his original point.
Also that's one fast river =P
Congratulations! You are the winner of Week#2. You were able to answer both questions the fastest. The payout was only 0.17 SBD, but at least that is something! Thanks for playing. And don't forget to check out this week's post.
May the force be with you.
Jack takes 30min to cross the river. He's 4832.146m from his original position.
Good job, @macro-d! You got both of the questions correct. However, you were just a bit slower than @cygon on the draw this week. But you still got a 100% upvote by me, so at least that's something! Check out this week's post for another chance to win!
and he'll have moved 2087m on the other side.
Thanks for trying, @alshabaz! You got the first question correct, so I gave you an upvote! To check out the other answer and see the new problems, check out this week's post!
@yoghurt, thanks for playing! You got the first question correct, so I gave you an upvote! To see the explanations for problems and to see the new problems for this week, check out this post.
1- May the force be with you.
@gduran, thanks for your entry! You got the first question correct, but the second question was oh-so-close! I am interested at where you got the extra 4 seconds? Anyway, here is the new post for another chance to win!
May the force be with you.
It takes Jack 30min to cross. He ends up 4140m to the east as well, so 4222.89m from his original point.
Thanks for entering, @lexyflexy! Your first answer was correct, and the first part of the second answer was also correct. For that, I gave you a 100% upvote! Check out the new questions for this week here.
