Question

A scooter covers a distance of 3 km in 5 minutes.calculate his speed in km/hr

Answer 1

5 min = 5 min × 1 hour / 60 min = (1 / 12) hour

Speed = Distance / Time
= (3 km) / (5 min)
= (3 km) / [(1 / 12) hour]
= 36 kmph

∴ Speed of scooter is 36 kmph

Answer 2

1 min = 1/60 hr
5 min = 5/60 = 1/12 hr

So in 1/12 hr -- 3 km
In 1 hr = 3 x 12 = 36 km


So required speed in km/hr is 36 km/hr

Hope This Helps You!
