Question

4) A car covers a total of 200 kilometres in 4 hours. What is the average speed of the
(a)40 km/hr
(b50 km/hr
(c) 100 km/hr
(d)800 km/hr​

Answer 1

Explanation:

given

A car covers a total of 200 kilometres in 4 hours

average speed = total distance ÷ total time

= 200 ÷ 4

= 50 km/h

Answer 2

Answer:

The average speed, s, of the car measured is $50km/hr$.

Therefore, option b) $50km/hr$ is correct.

Explanation:

Given,

The distance travelled by car, d = $200km$

The time taken by the car, t = $4hrs$

The average speed of the car, s =?

As we know,

• The average speed is the distance per unit of time.
• $s = \frac{d}{t}$

After putting the given values in the equation, we get:

• $s = \frac{200}{4}$
• s = $50km/hr$

Hence, the average speed of the car, s = $50km/hr$.
