Question

. A car takes 30 minutes to cover a distance of 25 km. Calculate its speed in km/h.​

Answer 1

•Speed is defined as the rate of change of distance.

Speed = distance/ time

•Here, the given time is in minutes

so we will convert it into hour

As we know 1 hour has 60 minutes

Therefore, 30 minutes = 0.5 Hour

Distance is given to be 25 km.

Speed = 25/0.5

= 50 km/hr

The speed will be 50km/hr

Answer 2

Given:

A car takes 30 minutes to cover a distance of 25 km.

Find:

Calculate its speed in km/h.​

Solution:

Speed is defined as the rate of change of distance.

$Speed=\frac{Distance}{Time}$

Here, the given time is in minutes

so we will convert it into an hour

As we know 1 hour has $60 minutes$

Therefore, 30 minutes $= 0.5 Hour$

Distance is given to be $25 km.$

Speed $= \frac{25}{0.5}$

$= 50 km/hr$

Hence, The speed will be $= 50 km/hr$
