A car covers a distance of 300 m in 20 seconds. Calculate the speed of the car. Options: A . &nbsp25 ms−1 B . &nbsp20 ms−1 C . &nbsp10 ms−1 D . &nbsp15 ms−1

Answer: Option D : D Given, distance travelled by the car = 300 m and the time taken = 20 s . We know, s p e e d = d i s t a n c e t i m e ⇒ s p e e d = 300 20 = 15 m s − 1 . ∴ Speed of car is 15 m s − 1

A car covers a distance of 300 m in 20 seconds. Calculate the speed of the car.

Question

A car covers a distance of 300 m in 20 seconds. Calculate the speed of the car.

Options:

A . 25 ms−1

B . 20 ms−1

C . 10 ms−1

D . 15 ms−1

Answer: Option D
:
D
Given, distance travelled by the car

= 300 m

and the time taken

= 20 s

.
We know,

s p e e d = \frac{d i s t a n c e}{t i m e}

\Rightarrow s p e e d = \frac{300}{20}

15 m s^{- 1}

∴

Speed of car is

15 m s^{- 1}
