At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is a moving conveyor belt
Amanda [17]

Answer:

The time taken is t_s = 31.16 s

Explanation:

From the question we are told that

   The length of the speed ramp is L = 104m

     The speed of the speed ramp is v_r  = 2.1 m/s

      The time taken to cover the distance is t = 84 s

     

The walking speed( when not on the speed ramp)  required to  cover the 104m is mathematically represented as

                     v_w = \frac{L}{t}

Substituting values

                      v_w = \frac{104}{84}

                            = 1.238 m/s

The speed required to cover the 104m distance when on a speed speed ramp  is mathematically represented as

     v = The\ walking\ speed  +  speed \ of \ the \ speed \ ramp

 substituting values

               v = 2.1 + 1.238

               v = 3.338 m/s

Now the time taken to travel the 104m distance when walking on the speed ramp is mathematically evaluated as

                t_s = \frac{L}{v}

                     = \frac{104}{3.338}

                     t_s = 31.16 s
