Question

A train goes at a constant speed. It can travel 150 miles in 2 1/2. How long will it take that train to travel 100 miles

Answer 1

1 2/3 hours

Explanation:

At constant speed, the time is proportional to the distance.

time/distance = 2.5 h/150 mi = x /100

x = 100(2.5/150) h = 5/3 h = 1 2/3 h

It will take the train 1 2/3 hours to travel 100 miles.
