Question

Kelly drove 440 miles in 8 hours. Alberto drove 468 miles in 9 hours. Both drove at constant speed. Who drove farther in 1 hour? How many miles farther?

Answer 1

Kelly drove 55 miles in one hour.
440 ÷ 8= 55

Answer 2

Kelly drove 3 miles farther than Alberto.

Explanation:

Consider the provided information.

Kelly drove 440 miles in 8 hours.

This can be written as:

440 miles = 8 hours

Divide both sides by 8.

440/8 miles = 8/8 hours

55 miles = 1 hours

That means Kelly drove 55 miles in 1 hour.

Alberto drove 468 miles in 9 hours.

This can be written as:

468 miles = 9 hours

Divide both sides by 9.

468/9 miles = 9/9 hours

52 miles = 1 hours

That means Alberto drove 52 miles in 1 hour.

Hence, Kelly drove farther than Alberto.

To find how much simply subtract them.

55 miles - 52 miles = 3 miles

Therefore, Kelly drove 3 miles farther than Alberto.
