Atraveler 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?

 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

Adding (1) and (2), we get

Subtract (2) from (1), we get

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

The speed of the moving walkway= 2 ft/s

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
