This problem describes two points in a route of 4 hours. He went through 68 miles after the first two hours, and 132 miles after 4 hours of driving. We need to calculate the average rate of change.
The average rate of change is the division between the total distance and the time it took to travel that distance, so we have:
The average rate of change is equal to 33 miles per hour.

Answer:
The two pieces of information are needed to prove that line AB is a perpendicular bisector of line CD are:
m∠AGD = 90° ⇒ B
CG = GD ⇒ C
Step-by-step explanation:
If line m is the perpendicular bisector of line AB and intersect it at point D
- The angles around point D are right angles (the measure of each one 90°)
Let us use these facts to solve our question
Look at the given figure
∵ Line AB is the perpendicular bisector of line CD
∵ Line AB intersects line CD at point G
∴ G is the midpoint of CD
→ That means the point G divides the line CD into two equal parts
CG and GD
∴ CG = GD
∵ AB ⊥ CD at G
∴ ∠AGD and ∠AGC are right angles
→ the measure of the right angle is 90°
∴ m∠AGD = m∠AGC = 90°
The two pieces of information are needed to prove that line AB is a perpendicular bisector of line CD are:
m∠AGD = 90° ⇒ B
CG = GD ⇒ C
Heyooooooooooo. I’m bored.
