An airplane flies at a speed of 700 m/s. If the distance around the Earth is approximately 40,000,000 meters, how long will it take the airplane to fly around the Earth?
Answer explanation
To find the time, divide the distance by speed: 40,000,000 m ÷ 700 m/s = 57,142.86 seconds. Thus, it will take approximately 57,143 seconds for the airplane to fly around the Earth.
