Question

A teacher is moving with a velocity of 500 cms-¹ calculate its value is kmh-¹​

Answer 1

Answer:

18 KM/HR

Explanation:

First convert speed given in cm/s to m/s.

i.e. 1 m = 100 cm

therefore speed of tractor is 5 m/s.

now converting m/s to km/hr

1 hour = 3600 seconds

so 1 second = 1/3600 hour

 

1 km = 1000 m

so 1 m = 1/1000 km

now 5 m/s =  

i.e speed of tractor is 18 km/hr
