Answer 1

Answer:B

Explanation:

.03 of an hr is 2 mins and if it takes 2 mins to drive 4 miles enter it in pace calulator you are going 120mph so the closest to 120 is 133mph

Answer 2

The kid is breaking the speed limit of 45 miles/hr since he is going at 133.3 miles/hr.

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Since the distance to the mall is 4 miles, the time taken is 0.03 hours, hence the speed is:

Speed = distance / time

Speed = 4 miles / 0.03 hours

Speed = 133.3 miles/hr

Hence the kid is breaking the speed limit of 45 miles/hr since he is going at 133.3 miles/hr.
