Answer:

The unit rate is 4.5 days per trip

Step-by-step explanation:

So the equation would be 90 divided by 20

Simplified it is the same thing as 9 divided by 2

90 divided by 20 is 4.5

Answer:

4.5/1

Step-by-step explanation:

First, I found that 10 was the first factor or whatever I could find, so our new ratio is:

9/2

This is obviously not the unit rate, but if we divide by 2 we get:

4.5/1

So our unit rate is 4.5/1
