A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The​ traveler's ground speed is 1 ​ft/s against the walkway and  5 ft divided by s with the walkway. What is the​ traveler's speed off the​ walkway? What is the speed of the moving​ walkway?

Respuesta :

Answer:  The​ traveler's speed off the​ walkway= 3 ft/s

The speed of the moving​ walkway= 2 ft/s


Step-by-step explanation:

Given: A traveler is walking on a moving walkway in an airport.

Let 't' be the​ traveler's speed off the​ walkway and 'w' be the speed of walkway.

Then the​ traveler's ground speed against the walkway (t-w)= 1 ​ft/s

And the​ traveler's ground speed  with the walkway (t+w)= 5 ft/s

thus we get the following equations [tex]t-w=1..........(1)\\t+w=5.............(2)[/tex]

Adding (1) and (2), we get

[tex]2t=6\\\Rightarrow\ t=3[/tex]

Subtract (2) from (1), we get

[tex]2w=4\\\Rightarrow\ w=2[/tex]

Therefore, the​ traveler's speed off the​ walkway= 3 ft/s

The speed of the moving​ walkway= 2 ft/s
