Given information:
The term given in the question- unit rate.
Consider the term unit rate given in the question.
Definition of a unit rate:
A unit rate is a rate that has a denominator of 1 when expressed in fraction form.
Unit rates are often expressed using the word per, which means "for every".
Consider the following example of unit rate:
A tap can fill a water tank of 60 litres in 6 hours.
Write a rate comparing the total litres of water to the total time taken in hours.

R a t e = \frac{60 l i t r e s}{6 h o u r}

Rewrite the rate so the denominator is 1.

\frac{60 l i t r e s}{6 h o u r s} = \frac{60 l i t r e s \div 6}{6 h o u r s \div 6}

[Divide the numerator and denominator by 6.]

= \frac{10 l i t r e s}{1 h o u r}

[simplify]
Hence,
The amount of water filling the tank is 10 litres per hour.

Step 1
Write down a metric comparing the total number of liters of water to the total hours spent.

Rate = \frac{60 litres}{6 hour}

\frac{60}{6} = \frac{60 \div 6}{6 \div 6}

= \frac{10 liters}{1 hour}

Answer: the amount of water the tank is 10 litres por hour.
