Question

An aeroplane flew from Qatar to Bahrain. The distance flown was 135 km. The average speed was 180 km/h. Work out the time taken. Give your answer in minutes

Answer 1

Given:

The distance flown was 135 km.

The average speed was 180 km/h.

To find:

The time taken by the airplane.

Solution:

We know that,

`Speed=(Distance)/(Time)`

`Time=(Distance)/(Speed)`

Putting Distance = 135 and Speed = 180, we get

`Time=(135)/(180)`

`Time=0.75`

The time taken by the airplane is 0.75 hours.

We know that,

1 hour = 60 min

0.75 hour = 0.75 × 60 min

0.75 hour = 45 min

Therefore, the time taken by the airplane is 45 min.
