Question

A car covers 25 kms in 10 minutes. Calculate its speed in m/s​

Answer 1

From the given question the correct answer is:

The speed is 41.6 m/s.

Given:

Distance=25kms

Time=10 minuses

To find : speed in m/s

Solution:

We have to find speed in m/s​

so first, t we have to convert Kms into meters.

and minutes into second

so,

1 km have 1000 meters.

1 minute has 60 seconds.

then,

25  × 1000=25000 m.

10×60= 600 seconds

Now ,

we have to find speed:

Speed=distance / Time

          =25000/600

            =41.6 m/s

The speed is 41.6 m/s.

Answer 2

Answer:

Explanation:

From the given question the correct

answer is: The speed is 41.6 m/s.

Given:

Distance=25kms

Time=10 minuses

To find speed in m/s

Solution:

We have to find speed in m/s so first, t we have to convert Kms into meters.

and minutes into second

so,

1 km have 1000 meters.

1 minute has 60 seconds.

then,

25 * 1000 = 25000m .

10×60= 600 seconds

Now,

we have to find speed:

Speed-distance / Time

=25000/600

=41.6m/s
