Raheem is on the road trip from Ohio to Vermont, a distance about 700 miles. During the first two hours of this trip, his distance from Vermontis given by the function x(t)= 700-30t-15t^2. Write a rational function that expresses the average rate of change of Raheem's distance from Vermont during during the first t hours of his trip.
Accepted Solution
A:
Answer: d. none of theseStep-by-step explanation:The average rate of change of x(t) over the interval [0, t] is given by ... average rate of change = (x(t) -x(0))/(t-0) = ((700 -30t -15t^2) -(700))/t = (-30t -15t^2)/t = -30 -15t . . . . . . . . . neither version of this answer matches any choice
