Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate (Below). Machine A covers 5/8 square feet in 1/4 hour or Machine B covers 2/3 square feet in 1/5 hour.

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.

Step-by-step explanation:

The unit rates for both machines need to be calculated first.

The unit rate will be calculated as:

For Machine A:

Area Covered = 5/8

Time = 1/4

The unit rate will be:

For Machine B:

Area Covered = 2/3

Time = 1/5

As it can be seen that unit rate for Machine B is greater than Unit Rate of Machine A.

Hence,

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.
