Question

Sarthak takes 80 steps per minute if the length of each step is 40cm find speed in kilometre per hour

Answer 1

Find the number of steps taken in 1 hour:

1 min = 80 steps

1 hour = 80 x 60 = 4800 steps

Find the total distance:

1 step = 40 cm

4800 steps = 40 x 4800 = 192,000 cm

Convert the cm to km:

192,000 cm = 192,000 ÷ 100,000 = 1.92 km

1 hour = 1.92 km

⇒ Speed = 1.92 km/h

Answer: 1.92 km/h
