Answer:
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
