Question

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

Answer 1

For distance in 1 minute, divide the distance for 6 minutes by 6 minutes:

7.5 km / 6 minutes = 1.25 km per minute.

For 100 minutes, multiply distance per minute by total minutes:

1.25 km per minute x 100 minutes = 125 km

Answer 2

Answer:

1.25 km in 1 minute

125 km in 100 minutes

Step-by-step explanation:

Find its speed in km/min by dividing the km by number of minutes:

7.5/6

= 1.25

So, the train goes 1.25 km in 1 minute.

Using this speed, find how far it goes in 100 minutes, by multiplying the speed by 100:

1.25(100)

= 125

So, in 100 minutes, the train goes 125 km.
