A train left for Houston, and 5 hours later, a car traveling 74 mph tried catching up to the train. After8 hours, the car caught up. What was the train's average speed?

train speed = x

car = 74

train head start = 5 x

closing speed = car - train = 74 - x

closing speed for 8 hours covers the head start distance 5x = (74-x) 8 solve for x = 45.53 m/hr
