The complete question is
<em>"Morgan has an 8 1/2-foot board that must be cut into boards that are 5/6 feet long. How many of the smaller boards can he get from the 81/2-foot board?"</em>
<em />
First, we need to transform the mixed number into a fraction:
According to the problem, each smaller board is 5/6 feet long.
So, we need to divide to know the total number of smaller board Morgan can get:
Therefore, Morgan would get 10 complete smaller boards from the bigger one.

We know that area of a triangle is given as
substituting our given values we have
re-arranging we have
we can now find two factors that will add up to give 2 and multiply to give -168
they are 14 and -12
The possible base of the triangle is 14 in
and the height is
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
