A) 0.75 miles per hour
B) 1 mile per hour
C) 1.5 miles per hour
D) 2 miles per hour
E) None of the above

Answer 1

Mark's rate of change for both days is 0.75 miles per hour (A).

Step-by-step explanation:

To find Mark's rate of change for both days, we need to calculate his speed or rate using the formula:

Rate = Distance / Time

For Saturday, Mark hiked 4.5 miles in 6 hours. So, his rate of change is:

Rate = 4.5 miles / 6 hours = 0.75 miles per hour (A)

For Sunday, Mark hiked 1.5 miles in 2 hours. So, his rate of change is:

Rate = 1.5 miles / 2 hours = 0.75 miles per hour (A)

Therefore, Mark's rate of change for both days is 0.75 miles per hour (A).
