Question

Sarthak takes 80 steps per minute. if the length of each step is 40 cm, tind his speed in km/h. solve by proportional method​

Answer 1

Sarthak takes 80 steps per minute.

The length of each step is 40 cm.

Therefore distance travelled by Sarthak in 1 minute

= 80 × 40 cms = 3200 cms

100 cms are equal to 1 meter, therefore 3200 can will equal to

= 3200/100 = 32 meters

His speed is 32 meter per minute.

Now to convert this meter per minute speed to kilometer per hour.

1 meter per minute = 0.06 kilometer per hour

Thus 32 meter per minute = 0.06 × 32 = 1.92 kilometer per hour

Thus the speed of Sarthak is 1.92 kliometer per hour
