A moving beltway at an airport has a speed υ 1 and a length L. A woman stands on the beltway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the beltway with a speed of υ 2 relative to the moving beltway. (a) What time interval is required for the woman to travel the distance L? (b) What time interval is required for the man to travel this distance? (c) A second beltway is located next to the first one. It is identical to the first one but moves in the opposite direction at speed υ 1 . Just as the man steps onto the beginning of the beltway and begins to walk at speed relative to his beltway, a child steps on the other end of the adjacent beltway. The child stands at rest relative to this second beltway. How long after stepping on the beltway does the man pass the child?

You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground.
How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway?
Express your answer using one significant figure.
A moving walkway at an airport has a speed v1 and a length L. A woman stands on the walkway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the walkway with a speed of v2 relative to the moving walkway. (Use any variable or symbol stated above as necessary.)
(a) How long does it take the woman to travel the distance L?
(b) How long does it take the man to travel this distance?
