Answer:

Here's the right answer mate!

When the wheel rotates one revolution the point of the rim will travel a distance which is equal to circumference of the wheel circle.

Distance travel for one revolution = 2πr

Distance travel for one revolution = 2×10π = 20π cm.

The wheel rotates 5 revolutions per minute. So the distance travel by the point will be 20π × 500 = 100π

For one minute(60 seconds) the point travels 100picm distance.

So distance travelled in 2 seconds

= 100 × 2/60 = 10.47cm

So the answer is 10.47cm.
