Answer 2

Concept:

Speed is the ratio of the Total distance and Total time to cover the distance .

So In mathematical term we can write like, $\mathrm{Speed=\frac{Total ~Distance}{Total~Time}}$

Given:

Covering distance of the flight 7425 miles and average speed of the flight is 550 miles an hour.

Find:

The required flight time of this trip.

Solution:

To fly from LA to Sydney, a flight has to cover a distance of 7425 miles.

So, Total distance = 7425 miles.

Given the average speed of the flight is 550 miles per hour

So, flight covers 550 miles in 1 hour

Flight covers 1 miles in $=\frac{1}{550}$ hour

Flight covers 7425 miles in $=7425\times \frac{1}{550}=13.5$ hours

Hence the required flight time for the trip is 13.5 hour or 13 hours 30 minutes.
