<span>Average speed = distance over time so here
Speed = (22 1/2) / (1/3) = 67 1/2 miles per hour</span>
Part B. f(x) = 90 + 0.11x
f(300) = 90 + 0.11(300) = 90 + 33 = $123
f(300) represents the total cost, in dollars, for renting a car for a week and driving it for 300 miles.
<h3>
Answer: 208</h3>
Work Shown:
S = sum of the first n terms of an arithmetic sequence
S = (n/2)*(firstTerm + nthTerm)
S = (8/2)*(firstTerm + 8thTerm)
S = 4*(6 + 46)
S = 4*52
S = 208
