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

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

So, it's below the limit.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
