An airplane leaves London 11:30pm and reaches Ghana 4,415km/h away at 5:30am the next morning. Find correct to the nearest whole number, the average speed of the airplane.
The flight duration is (5:30 am - 11:30 pm) = 6 hours.
Average Speed = Total Distance / Total Time
Average Speed = 4415 km / 6 hours
= 735.83 km/h
≈ 736 km/h to the nearest whole number.
Therefore, the average speed of the airplane is approximately 736 km/h.
