A car travels 14 km in 12 minutes. Calculate the speed in km/h.

Academic Physics NCERT Class 7

Given: A car travels 14 km in 12 minutes.

To find: Speed in km/h

Solution:

We know, $Speed = \frac{Distance}{Time}$

Here time is given in minutes, we have to convert in hours.

$12 \ minutes = \frac{12}{60} \ hours$

$= \frac{1}{5} \ hours$

So, Speed = $14 \ Km \div \frac{1}{5} \ hours$

= 70 km/h
