Question

A plane covers 2,160 miles in 5.5 hours. what is the average speed of the plane to the nearest tenth?

Answer 1

2160 divided by 5.5 = 392.7 hopefully this is right!

Answer 2

Hence, the average speed of the plane is:

392.7 miles/hour.

Explanation:

The distance covered by a plane is: 2160 miles.

Also the time taken by the plane to cover this distance is: 5.5 hours.

Now, the average speed of the plane is the ratio of the total distance covered to the total time taken.

i..e

Speed=Distance/Time.

Hence,

`Speed=(2160)/(5.5)\\\\\\Speed=392.7\ miles\ per\ hour`

Hence, average speed is:

392.7 miles/hour
