Question

A train goes at a constant speed. It can travel 159 miles in 2 1/2 hours. What distance would it travel in 2 hours

Answer 1

127.2 miles

Explanation:

using the relationships

speed =
`(distance)/(time)` ( time in hours ) =
`(159)/(2.5)` = 63.6 mph

constant speed is 63.6 mph

then

distance = speed × time = 63.6 × 2 = 127.2 miles
