Question

An airplane flies 1980 km in 2.75 hours. What is its average speed in
kilometers per hour?

Answer 1

The average speed of the airplane is 720 kilometers per hour.

Step-by-step explanation:

To calculate the average speed of an airplane, we can use the formula:

Average speed = Distance / Time

In this case, the distance traveled by the airplane is 1980 km and the time taken is 2.75 hours.

Plugging these values into the formula, we get:

Average speed = 1980 km / 2.75 hours = 720 km/h

Therefore, the average speed of the airplane is 720 kilometers per hour.
