03

Step-3 – Explanation

Definition: A unit rate is given by a rate that has a denominator of1 unit.

Unit rates contain the word per, which means 鈥渇or every鈥�.

Example:

Let a plane covers 150 km in 30 minutes.

Then we write a rate for the speed of the plane using total distance to the total time taken in minutes.

Rate =.150km30min

Then we will rewrite the rate so the denominator becomes .

150km30min=150km梅3030min梅30[Dividethenumeratoranddenominatorby30.]=5km1min[simplify]

So, the speed of the plane is 5 km per minute.
