Hi,

D = r*t  This question sets up that the distance traveled is the same for each.

Question states: truck traveling at 60mph...left 2 hours later

Let (t + 2)and t represent the respective times traveled by the trucks

50mph(t+2) = 60mph*t

solving for t

50t + 100 = 60t

100 = 10t

10hr = t, time it will take for the truck traveling 60mph to catch up

CHECKING OUR ANSER

50mph*12hr = 60mph*10hr = 600mi (misc info as to the distance traveled by each)
