Answer:

The answer is: Plane A is faster, by 5 miles per hour.

Step-by-step explanation:

Plane A travels 2,800 miles in 5 hours.

Divide to get miles per hour:

2,800 / 5 = 560 mph

Plane B travels 3,885 miles in 7 hours.

Divide to get miles per hour:

3,885 / 7 = 555 mph

Plane A is faster, by 5 miles per hour.

Plane A is faster since it has a better speed than plane B.

Since Plane A travels 2,800 miles in 5 hours, the speed of plane A will be:

= 2800/5

= 560 miles per hour

Since Plane B travels 3,885 miles in 7 hours, the speed of plane B will be:

= 3885 / 7

= 555 miles per hour

Therefore, plane A is faster.
