I really need some help on this question

Leya [2.2K]

Answer:

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

$0.9\frac{km}{min}$

How many kilometers will the car travel in 5 minutes?

$4.5\ km$

Step-by-step explanation:

If we know:

$\frac{54\ km}{1\ hour}$

And there are 60 minutes in an hour:

$\frac{1\ hour}{60\ minutes}$

We can do:

$\frac{54\ km}{1\ hour} * \frac{1\ hour}{60\ minutes} = \frac{54\ km}{60\ minutes} = 0.9 \frac{km}{min}$

From here, we figure out the distance from minutes:

$0.9\frac{km}{min} * 5 = 4.5\ km$
