Question

A car covers 30 km in 3 hr 35 min . Find the speed of the car​

Answer 1

Answer:

In the first case,

time= 30min=30/60hrs=1/2hr.

Speed=60km/hr.

Therefore, distance=speed×time=60×1/2=30km.

In the second case,

distance is same=30km.

Time= 20 minutes=20/60hr=1/3hr.

Now,speed=distance/time=30/(1/3)=30×3=90km/hr.
