The speed limit on a road is 40mph. A scooter drives 7 miles in 12 minutes. Is the scooter breaking the speed limit?

No, the scooter is travelling at 35mph, therefore under the speed limit of 40mph

First of all, observe that 12 minutes are 1/5 of a hour.

The speed is the ratio between distance and time taken, so it is

[tex]s=\dfrac{7}{\frac{1}{5}}=7\cdot 5=35[/tex]

So, it's below the limit.
