Question

Two trains travel from New Orleans to Memphis in 5 h. The first train travels at a constant velocity of 80 mph, but the velocity of the second train varies. What was the second train's average velocity during the trip

Answer 1

Step-by-step explanation:

The first train travels at a constant velocity of 80 mph and it takes 5 h to cover the distance so distance between two station = 80 x 5 = 400 m

second train too takes 5 h to cover the same distance so its average velocity

= total distance / total time

= 400 / 5 = 80 m /h

average velocity = 80 m /h
