Question

A person drives 4 miles to the mall. If the speed limit is 45 miles/hr and the person

makes the trip in .03 hours. Is the person breaking the speed limit?
Yes, the person is going 150 miles/hr.
O No, the person is going 1 mile/hr.
Yes, the person is going 133 miles/hr.
O No, the person is going 40 miles/hr.

Answer 1

Answer: Third Option

Yes, the person is going 133 miles/hr.

Step-by-step explanation:

Remember that the average speed can be calculated as

`s = (d)/(t)`

Where s is the speed

d is the distance traveled

t is the time

In this case

`d =4\ miles\\`

`t=0.03\ hours`

Therefore

`s = (4)/(0.03)`

`s = 133.33\ miles/hr`

Remember that the speed limit is 45 miles/hr

So the answer is the third option "Yes, the person is going 133 miles/hr".
