Answer 1

Given

Circumference of unicycle = 2.8 m

To find

Distance benjamin travells in 100 seconds.

Solution

Distance covered in one second = circumference of tyre × no of revolution in one second.

Distance covered in one second = 2.8*1.5

= 4.2 m

Distance covered in 100 second = Distance covered in one second *100

Distance covered in 100 second = 4.2*100

= 420 m
