Question

A scooter covers a distance of 3 km in 5 minutes.calculate his speed in m/s

Answer 1

10 m/s is the speed acquired by the object

Answer 2

His speed is 10 m/s.

Given data:

Distance = 3 km

Time = 5 minutes

Solution:

The distance is given in kilometers which needs to be converted into meters, so,

d = 3 km = 3000 m

Similarly, time is given in minutes which needs to be converted into seconds, so,

t = 5 min = 5 × 60 = 300 sec

Therefore, the speed is calculated by  

$Speed = \frac{Distance}{Time}$

$\Rightarrow Speed = \frac{d}{t}$

$= \frac{3000}{300}$

$\Rightarrow Speed = 10 \ m/s$
