Question

What is the speed of a jet plane that flies 7200 km in 9 hours (in km/ hr)?

Answer 1

Answer:

800 km/hr

Explanation:

Distance travelled = 7200 km

Time taken = 9 hours

We know,

Speed = Distance/Time

Thus,

Speed of the jet plane

= 7200/9

= 800 km/hr

Answer 2

Given:

A jet plane that flies 7200 km in 9 hours.

To find:

The speed of the jet plane.

Solution:

To determine the speed of the jet plane we have to use the below formula as follows-

We know that-

Speed=Distance/time.

The distance travelled by the jet plane is 7200 km.

Again the time of travelling is 9 hours.

Hence putting value in the above formula we get-

Speed=7200/9

Speed=800.

Hence the speed of the jet plane is 800 km/hr.
