Question

A passenger jet flies from one airport to another 1273 miles away in 2.7 h. Find its average speed.​

Answer 1

Average speed of passenger jet

`s = 471.48\ mi/hr`

Step-by-step explanation:

Let s be the average speed of the passenger jet.

Given:

Distance from one airport to another airport
`d = 1273\ mi`

Total time taken
`t = 2.7\ hr`

We need to find the average speed of the passenger jet.

Solution:

Average speed formula:

The ratio of the total distance travelled by the object to the time taken to cover that distance.

`Average\ speed = (Total\ distance\ travelled)/(Total\ time\ taken)`

`s = (d)/(t)`

Substitute total distance and time value in above equation.

`s = (1273)/(2.7)`

`s = 471.48\ mi/hr`

Therefore, the average speed of the passenger jet is
`s = 471.48\ mi/hr`.
