Question 578387: Two cyclists start at the same point but travel in opposite directions. Cyclist 1 travels at 3 mph. Cyclist 2 travels at 4 mph. How long will it take before they are 16.8 mile apart? Answer by dfrazzetto(283) (Show Source):
You can put this solution on YOUR website!
When traveling in opposite directions, you can effectively add their speeds(velocities):
C1= 3mph
C2= 4mph
Aggregate speed = 3+4= 7mph
d=rt
16.8 = 7t
t = 16.8/7 = 2.4 hours
CHECK
3(2.4) + 4(2.4) = 16.8 √
