My first try was way off.
But now I get 1488.75 seconds
T = 2000 mph
A = 4000 mph
G = 24,000 mph
S = 2C + 300 miles
time for A to go to C = time for G to go to 2 S - 50 =
C/A = (2 S - 50)/G
S = 3C + 25 miles
C = 275 miles
D = 550 miles
S = 850 miles
time for T to go to S = S/T = (850/2000)3600 sec = 1530 sec
time for G to go to C = C/G = (275/24,000)3600 sec = 41.25 sec
1530 sec - 41.25 sec = 1488.75 sec.

Correct! 1488.75 is the right answer! :)
Well done.. :D
