Question

the speed of the racing car is 60 M per second what will be his speed in kilometre per hour

Answer 1

Speed of the racing car=60m/s

1m =1/1000 km

1s 1/3600 h

Speed of car in km /h =(60×3600)÷1000

=216km/h

Answer 2

The speed off the racing car is 216 km/h.

Explanation:

Given that the speed of the racing car is 60 m/s. We need to convert the speed into km/hr. For this, we must know the conversion from one unit to another.

As we know that,

1 km = 1000 m

And

1 hour = 3600 seconds

Therefore,

$60\ \dfrac{m}{s}=60\times \dfrac{0.001\ km}{(1/3600\ h)}\\\\60\ \dfrac{m}{s}=216\ km/h$

So, the speed off the racing car is 216 km/h. Hence, this is the required solution.
