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.
