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
Combine the x terms since they are like terms and combine the constant terms since they are like terms.
x + 3x = 4x
9 + 7 = 16
4x + 16

Answer:
We know that the angle of elevation is
θ
As trigonometry says,
tan
θ
=

Answer:
61
Step-by-step explanation:
Since we now that avalanches occur at 245 mph and that is 4 times as fast as a skier. So we can divide 245/4 = 61.25 ≈61
