A plane makes a return journey across the Atlantic Ocean, a distance
of 3800 km each way. From west to east the journey time is 6 hours
12 minutes. Because of the jet stream the plane takes 7 hours 18 minutes
to fly the same journey east to west.
Find the average speed of the plane for each crossing.

Answer:

Below in bold.

Step-by-step explanation:

6 hours 12 minutes = 6.2 hours

7 hours 18 minutes = 7.3 hours.

Average speed = distance / time

So for West to East,  average speed =  3800 / 6.2 = 612.9 km/hour.

- and  for East to West,  average speed =  3800 / 7.3  = 520.5  km/hour.

These values are correct to the nearest tenth.
