We have given,

The speed of the jet Alyssa flew on from Boston to London was 480

mph.

On her return flight, the speed of the jet was 600 mph with a tail

wind.

What is the average speed?

$average speed=\frac{a+b}{2}$

a=inital speed

b=final speed

add 600 and 480 then divide by 2

That can be given by

$=\frac{600+480}{2}\\\\=\frac{1080}{2}\\\\=540$

Alyssa's average speed on the round trip is 540mph.
