Question

Suppose you are on a conveyor belt walkway at an airport. The walkway is moving at 0.50 m/s. You walk backward at 0.80 m/s to hand your suitcase to a friend who is 3.0 m behind you. A security guard stands alongside the walkway watching this. What is your speed relative to the guard?
a. 0.30 m/s

Answer 2

A? How did you get that :)?

Answer 3

the belt is, lets say moving towards north at 0.5 m/s and you walking towards south at 0.8 m/s. Your relative speed will be 0.8 m/s - 0.5 m/s = 0.3 m/s
