Town B to Town C. What was Mr Ali's average
speed for the whole journey?

See Explanation

Step-by-step explanation:

Given

---------- A to B

---------- B to C

Required

Determine the average speed of Mr. Ali's journey

To do this, we have to calculate the total distance covered.

i.e.

Distance = Town A to B + Town B to C

The distance between the towns are not given. So, I'll make an assumption.

-------------------------------------------------------------------------------------------------------------

Assume:

Town A to B = 5km

Town B to C = 10km

-------------------------------------------------------------------------------------------------------------

Average Speed is then calculated as:

answer: -8.2562234e+13

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
