Answer
37.5
Work Step by Step
The car drove the first 150 miles in 5 hours and the second
150 miles in 3 hours,
- which means it drove 300 miles in 8 hours,
- for an average value of $\frac{300}{8}$ mi/hr =37.5 mi/hr. In
terms of average value of functions, the function whose
average value we seek is
v(t)=$[^{30,0 < t < 5}_{50,5
