Question

2 for what is the uni t rate if a fertiliser covers 3/8 ft² in 1/6 of an hour

Answer 1

We can find the unit rate as follows:

We can divide 3/8 by 1/6, and it will give us the unit rate by an hour:

`((3)/(8))/((1)/(6))=(3\cdot6)/(8\cdot1)=(18)/(8)=(9)/(4)=2.25`

Therefore, the unit rate is 2.25 ft^2/hour.

We need to remember that a unit rate is a rate with a unit in the denominator, in this case, one hour (or per hour).
