Question

Ryanair provides cheap flights in Europe but prides itself on their on-time record. Ryanair quotes a flight time of 2 hours, 5 minutes. Suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes.

What is the expected flight time in minutes?

Answer 1

The expected flight time is 2 hours 10 minutes

Explanation:

Given

`a = 2\ hours`

`b = 2\ hours\ 20\ mins`

Required

The expected flight time

To do this, we simply calculate the mean using:

`Mean = (a + b)/(2)`

So, we have:

`Mean = (2\ hours + 2\ hours\ 20\ mins)/(2)`

`Mean = (4\ hours\ 20\ mins)/(2)`

`Mean = 2\ hours\ 10\ mins`
