Complete question:
Tony went on holiday to Miami. He travelled from London by plane. The distance from London to Miami is 7120 km. The plane journey took 8 hours. Calculate the average speed of the plane.
Step-by-step explanation:
Average speed is the total distance covered per unit time.
Average speed = Total distance covered/ total time taken
Given;
Total distance travelled = 7120 km
Total time taken = 8 hours
Substituting the values;
Average speed = 7120km/8 hours = 890 km/h
Converting to m/s
= 890 ×1000m/3600s
= 247.22 m/s
Average speed = 890km/h = 247.22m/s
