Answer:
a. 0.6 h
b. 1.3 h
c. C -- No
d. 4.2 mi/h
Step-by-step explanation:
a. The relationship between time (t), speed (s), and distance (d) is ...
t = d/s
The time spent running 4 miles at 7 miles per hour is ...
t = (4 mi)/(7 mi/h) = (4/7) h ≈ 0.6 h
__
b. The time spent walking home is ...
t = (4 mi)/(3 mi/h) = 4/3 h ≈ 1.3 h
__
c. C -- No, less time is spent at 7 mi/h
__
d. The average speed is ...
s = d/t = (4 mi +4 mi)/(4/7 h +4/3 h) = (8 mi)/(40/21 h) = 4.2 mi/h

Considering the situation described, we have that:
a. x = 65 - 8 = 57.
b. You won the game, as you scored 137 and your friend 130.
<h3>What is the equation for the situation after five frames?</h3>
Your friend's score is of 65, and your score of x is 8 less than your friend, hence the equation is:
x = 65 - 8 = 57.
<h3>What are the final scores?</h3>
Your friend score doubled, hence his/her final score is:
2 x 65 = 130.
Your score increased by 80, hence your final score is:
57 + 80 = 137.
You won the game, as you scored 137 and your friend 130.
