An airplane travels about 1500 km in a straight line between Toronto and Winnipeg. However, the plane must climb
to 10 000 m during the first 200 km. Then
it must descend 10 000 m during the final
300 km.
question:
The airplane averages a speed of
600 km/h. Do climbing and descending
10 000 m add hours, minutes, or
seconds to the flight?
Please explain :)
