Acar cruises at a constant rate of 52 miles per hour. use front-end estimation to find an approximation of the time taken by the car to cover 620 miles. a. 10hr b. 12hr c. 16hr d. 20hr

Option B.

Step-by-step explanation:

It is given that a car cruises at a constant rate of 52 miles per hour. It means

Speed of car = 52 miles per hour

Using  front-end estimation, we need find the time taken by the car to cover 620 miles.

In front-end estimation, we approximate the data according to the first digit. So,

Speed of car = 52 miles per hour ≈ 50 miles per hour

Distance = 620 miles ≈ 600 miles

Formula for time:

Substitute distance=600 and speed=50 in the above formula.

The time taken by the car to cover 620 miles is approximate 12 hr.

Therefore, the correct option is B.
