The answer is 24 (proof in picture below)
Since
h(x) = g(f(x)), h'(x) = g'(f(x))×f'(x) (Chain rule).
Setting x=3 we get
h'(3) = g'(f(3))×f'(3)
Plugging in values we get
h'(3) = g'(4)×7
h'(3) = 2×7
h'(3) = 14

Answer:
5.5 miles over 2 hours--> 5.5/2= 2.75 miles per hour was his average walking speed. 5.5 miles over 2.5 hours --> 5.5/2.5= 2.2 miles per hour on the return trip meaning that his average speed was (2.75-2.2= 0.55) 0.55 miles per hour lower on the return trip
Step-by-step explanation:
I hope this helps you :)
