Question

I really need some help on this question

Answer 1

What is the car's rate in kilometers per minute?

`0.9(km)/(min)`

How many kilometers will the car travel in 5 minutes?

`4.5\ km`

Explanation:

If we know:

`(54\ km)/(1\ hour)`

And there are 60 minutes in an hour:

`(1\ hour)/(60\ minutes)`

We can do:

`(54\ km)/(1\ hour) * (1\ hour)/(60\ minutes) = (54\ km)/(60\ minutes) = 0.9 (km)/(min)`

From here, we figure out the distance from minutes:

`0.9(km)/(min) * 5 = 4.5\ km`
