Question

Calculate the speed of a car that covers a distance of 108km in 30 mins

Answer 1

The speed of the car is 60 m/s

Explanation:

The speed of an object is a scalar quantity telling "how fast" the object is moving, regardless of its direction. It can be calculated as follows:

$speed=\frac{d}{t}$

where

d is the distance covered

t is the time taken

For the car in this problem, we have

$d=108 km =1.08\cdot 10^5 m$ is the distance covered

$t=30 min \cdot 60 =1800 s$ is the time taken

Subsituting into the equation, we find the speed:

$speed=\frac{1.08\cdot 10^5}{1800}=60 m/s$
