Question

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

Answer 1

Answer:

1.92 km/h

Step-by-step explanation:

80 steps per minute = 80 x 60 steps per hour

Therefore, 4800 steps per hour

each step is 40 cm means 40 x 4800 steps = 192000 cm total distance in one hour.

Now, 100cm = 1m and 1000m = 1km

That's why divide 192000 with 100 then with 1000

You'll get answer as

$\frac{192000}{100 \times 1000} = \frac{192000}{100000} = 1.92$
