Question

A train is moving at uniform speed of 90 Km/ hr. How far will it travel in 20 minutes? *

Answer 1

Answer:

First, convert the given information in same unit.

Let us convert minutes in hours.

1hour = 60minutes

So, 20 minutes => 20/60 = 1/3hours

We know that,

Speed = distance/ time

90 = distance / (1/3)

distance = 90× (1/3)

Distance = 30km

Answer 2

Given,

A train is moving at a uniform speed of 90 Km/hr.

To find,

Total distance covered by the train in 20 minutes.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically,

speed (s) = distance traveled (d)/time of journey(t)

=> Distance traveled (d) = speed (s) x time of journey(t)

{Statement-1}

According to the question;

Total distance covered by the train in 20 minutes

= speed (s) x time of journey(t)

= 90 Km/hr × 20 minutes

= 90 Km/hr × (20/60) hours

{Since 1 hour = 60 minutes

=> 1 minute = 1/60 hours}

= 90 Km/hr × 1/3 hours

= (90/3) Km

= 30 Km

Hence, the total distance covered by the train in 20 minutes is 30 Kms.
