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

x/3-10=8

x/3=18

x=48
