calculate the unite rate for machine A and B. determine with is greter rate.

Question

Machine A covers 5/4square feet in 1/4hour or machine B covers 2/3feet in 1/5 Hour

Answer 1

Dear Goodness

The unit rate for Machine A is calculated as:

Covered Area / Time to do it = (5/4) / (1/4) = (5*4) / (4*1) = 20/4 = 5 squared feet per hour

The unit rate for Machine B is calculated as:

Covered Area / Time to do it = (2/3) / (1/5) = (2*5) / (3*1) = 10/3 = 3.3 squared feet per hour

Machine A has higher unit rate than Machine B
