Asked by Haley

Two trains are traveling opposite directions. One train travels at a speed of 90 mph. The second train travels at a speed of 95 mph. The 2 trains travel for three hours. How far apart are the 2 trains?
Answered by Haley
I got 555 mph but I don't know if it's correct

90t+95t = 90(t-3)+95(t-3)+d
90t+95t = 90t+95t-270-285+d
0 = -555 + d
d = 555 [miles]

You got the number correct but the unit wrong. It should be miles, not miles/hour.
