Question

Calculate the linear speed of a bicycle with 26-inch wheels being pedaled at a rate of 200 revolutions per minute. Express your answer in inches per minute rounded to the nearest whole number. (Hint: The diameter of the wheel is 26 inches.)

I got: linear speed=r•w
r=13 w=200
linear speed= 2600 inches per minute ???????
Is this correct?

Thank you SO much!

Answer 1

26π in/rev * 200rev/min = 26π/200 in/min

w is not 200. It is 200*2π radians/min

Answer 2

So the answer would be .408 inches/minute?

Answer 3

Oww! My bad! Should have caught my typo.

26π*200 in/min

The ridiculous speed of less than 1/2 inch per minute should have caught your eye!

Answer 4

shiii idk
