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 in 100 seconds

Answer 1

Given

cir. = 2.8 m

n = 1.5

s = 100s

total revolution = n* s

= 1.5 * 100

= 150

d = cir. * total revolution

= 150*2.8

= 420 m

the ans is 420m
