Question 492251: Train speeds: A train leaves Cincinatti at 2:00 pm. A second train leaves the same station in the same direction at 4:00 pm. The second train travels 24 mph faster than the first. If the second train overtakes the first at 7:00 pm, what is the speed of each of the two trains?
I need to know how to set this problem up-thank you

the 1st train travels for 5 hr (7:00 - 2:00)
the 2nd train travels for 3 hr (7:00 - 4:00)
when the 2nd overtakes the 1st, they have traveled the same distance

r * t = d ___ R1 * 5 = R2 * 3

R1 + 24 = R2

solve using substitution
