Question

a cyclist cycles at 21 km per hour. how long will he take to cover a distance of 700 metres ans is 2 min
​

Answer 1

Step-by-step explanation:

speed of the cyclist = 21km/hr or 21000m/60mins

distance= 700m

so time taken = distance by speed

= 700/21000 = 1/30hr or 1/30 X 60 minutes = 2 mins

Answer 2

Answer:

21 kilometers per hour is equal to 21,000 meters per hour (given than 1 kilometer = 1,000 meters).

This is also equivalent to 21,000 meters per 60 minutes (given that one hour = 60 minutes).

To give us the velocity on how many meters it travels in a minute, we divide 21,000 by 60. This gives us a speed of 350 meters per minute.

This means that the cyclist will cover the distance of 700 meters in two minutes IF his starting speed is 21 kilometers per hour and not at 0.
