Question

Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.

Answer 1

Machine B

Explanation:

Since, Machine A covers
`(5)/(8)` square feet in
`(1)/(4)` hours,

Rate at which the Machine A is covering =
`((5)/(8))/((1)/(4))`

=
`(5)/(8)* (4)/(1)`

= 2.5 square feet per hour

Machine B covers
`(2)/(3)` square feet in
`(1)/(5)` hours,

Rate at which the Machine B is covering =
`((2)/(3))/((1)/(5))`

=
`(2)/(3)* (5)/(1)`

=
`(10)/(3)`

= 3.33 square feet per hour

Therefore, Rate of Machine B is greater.
