Question

A train at a constant speed and goes 7.5 kilometers in 6 minutes. At the rate:

How far does the train go in 1 minute?
How far does the train go in 100 minutes?

Answer 1

The distance covered by a train in 1 minute = 1.25 kilometers

The distance covered by a train in 100 minutes = 125 kilometers

Explanation:

The distance covered = 7.5 kilometers

Time taken = 6 minutes

Calculating unit rate

unit rate = 7.5 kilometers / 6 minutes

= 1.25 kilometers per minute

Thus,

The distance covered by a train in 1 minute = 1.25 kilometers

and

The distance covered by a train in 100 minutes = 1.25 × 100

= 125 kilometers
