Answer 2

Given : Rizwan covers 1200 m in 4 minutes on his bicycle.

To Find :  Speed in km/hour.​

Solution:

Rizwan covers 1200 m in 4 minutes on his bicycle.

Distance = 1200 m

1000 m = 1 km

Hence Distance = 1200/1000 km = 6/5  km

Time = 4 mins

1 hr = 60 mins

=> Time = 4/60  hrs  = 1/15  hrs

Speed = Distance / Time

= (6/5)/(1/15)

= 6 * 15 / 5

= 6 * 3

= 18  km/hr

Speed in km/hour  = 18
