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
