Answer:
B) 5 hours
Step-by-step explanation:
First, find the amount of mph between 60 and 80:
80 - 60
= 20 mph
Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:
20/4
= 5
So, the correct answer is B, 5 hours
<h3>
Answer: Choice (d)</h3>
Explanation:
To reflect over the y axis, we apply this rule

which says to flip the sign of the x term but keep the y coordinate the same.
