Find the speed of each train.

Question

The speed of train A is 6 mph slower than the speed of train B. Train A travels 190 miles in the same time it takes train B to travel 220 miles.

Answer 1

V_a=V_b-6

V_at=(V_B-6)t=190

V_bt=220

(V_b-6)t-V_bt=190-220

-6t=-30

t=5

V_b*5=220

V_b=44

V_a=V_b-6=44-6=38
