Question

A car travels 420 km in 6 hours. What is its speed in km/hr?

Answer 1

Given:

A car travels 420 km in 6 hours.

To find:

The speed of the car in-unit km/hr.

Solution:

The speed of the car is 70 km/hr.

To answer this question, first of all, we should know that if an object travels or covers distance 'd' in time 't', then its speed is given by:

$= \frac{d}{t}$

Now,

proceeding to the solution, we have

Distance travelled by car = 420 km

The time that was taken by the car to cover 420km = 6 hours

So,

The speed of the car

$= \frac{420}{6}$

$= 70 km/hr$

Hence, the speed of the car is 70 km/hr.
