A kid drives 4 miles to the mall. If the speed limit is 45 miles/hr and the kid makes the trip in .03 hours, is
the kid breaking the speed limit?
a. No, he is going 1 mile/hr.
b. Yes, he is going 133 miles/hr.
c. No, he is going 40 miles/hr.
d. Yes, he is going 150 miles/hr.

Respuesta :

Answer:

b

Step-by-step explanation:

0.03 hours= 1.8 minutes

4 miles in 1.8 minutes is not 45 miles per hour
B. Yes, he is going 133 mph

Explanation:

0.03 Hours = 1.8 Minutes

Set up a ratio.

1.8 Minutes for every 4 Miles

Therefore,

60 Minutes for every 133 Miles

I multiplied by 33.3 because the problem asks for the amount every hour, and to get from 1.8 Minutes to 60 Minutes we multiple by 33.3. Therefore, we must also multiply 4 by 33.3.

Yes, this exceeds the speed limit and is around 133. Therefore, the answer is B.
