Question 5750
You need the distance formula. d=rt
Train A = 5 miles/h
Train B = 6 miles/h
<--Train A at 5m/h for 2 h-----|--5 miles---|-----Train B at 6m/h for 2 h----->
So, the total distance is:
Distance of train A + 5 miles + Distance of train B = Total distance
(5*2)+5+(6*2) = x
10+5+12=x
x=27
After two hours they are 27 miles apart.
I hope this helps
