Question

good morning :) At the carnival, the Tea cups spin at a rate of 10 rpm. How long will it take for the Tea cups to spin 43.5 times? A. 435 minutes B. 44.5 minutes C. 43.5 minutes D. 4.35 minutes

Answer 1

Hey!

Your answer is D!

Explanation:

To do this...

43.5 / 10= 4.35!

So it is 4.35 minutes!

Answer 2

Option D

Explanation:

Using Unitary Method:

10 rotations = 1 minute

=> 1 rotation = 1/10 minute

Multiplying both sides by 43.5

=> 43.5 rotation =
`(43.5)/(10)` minutes

=> 43.5 rotation = 4.35 minutes
