# Lauren's SUV was detected exceeding the posted speed limit of 60 kilometers per hour, how many kilometers per hour would she have been traveling over the limit if she had covered a distance of 10 kilometers in 5 minutes?

$60 \text{km/hr}$

#### Explanation:

First convert her speed into km/hr.

There are 60 min in 1 hr so 5 min = 5/60 = 1/12 of an hour.

So her speed will be dist/time = $\frac{10}{\frac{1}{12}} = 120 \text{km/hr}$

So she exceeds the limit by $120 - 60 = 60 \text{km/hr}$
