Question

Benjamin is riding a unicycle. The tire of his unicycle has a circumference of 2.8m, and the tire revolves 1.5 times per second.
What is the distance Benjamin travels in 100 seconds?

Answer 1

Answer:

◾The wheel makes 1.5 revolutions per second. Each revolution travels 2.8 m.

Answer 2

Step-by-step explanation:

ANS.

4.4 m/s

SOLUTION

Given, inner diameter =50 cm, thickness of wheel =10 cm

Radius of the wheel =[12(50)+10]=35 cm

Distance travelled in one round

=2×227×3 cm

=220 cm =2.2 m

In five seconds, there are 10 revolutions.

Therefore, speed of the bicycle =105×2.2 m/sec

=4.4 m/sec
