Question

A wheel rotates 10 times every minute and move 20 cm during each rotation. How many cms does
the wheel move in 1 hour?

Answer 1

The distance moved by the wheel in 1 hour is 12000 cm.

Given:

A wheel rotates 10 times every minute. It moves 20 cm during each rotation.

To Find:

We need to find the distance moved by the wheel in 1 hour.

Solution:

Every minute wheel moves 10 times. Then for an hour, it rotates

$= 60 \times 10$

$= 600 \: times$

Each time it rotated, it covered 20 cm.

For 600 rotations it covers a distance of

$= 600 \times 20$

$= 12000$

Therefore, the wheel covers a distance of 12000cm in an hour.
