A travelers ground speed is 2 feet per second against the walkway and 8 feet per second with the walkway, what is the travelers speed off the walkway, what is the speed of yhe walkway

The traveller's speed is 5ft/s and the walkway speed is 3ft/s

Step-by-step explanation:

Given

Represent the traveller's speed with T and the walkway's speed with W.

When the traveller walk against the walkway, we have:

---- i.e. 2ft/s against the walkway

When the traveller walk with the walkway, we have:

---- i.e. 8ft/s with the walkway

Required

Solve for W and T

--- (i)

--- (ii)

Add (i) and (ii)

Divide both sides by 2

Substitute 5 for T in (ii)

Make W the subject

Hence, the traveller's speed is 5ft/s and the walkway speed is 3ft/s
