Question

4. A cyclist covers a distance of 20 km in 40
minutes. What is his speed? Calculate it in km/h
also.

​

Answer 1

Explanation:

If answer needed in m/s

Convert distance to meters and time to seconds.

Thus dist.=1500 meters

Time=150 seconds.

Speed=1500/150=10 m/s

Convert distance to kilometers and time to hours.

Thus dist.=1.5km and time-2.5/60 hrs.

Thus speed=1.5*60/2.5=36 km/hr.

Answer 2

Answer:

36 km/h

Explanation:

distance =1500 m

T=150

Speed =1500/150 = 10 m/s

Convert distance to km and time

D =1.5 km and time = 25/60

So, 1.5*60/25 = 36 km/h
