Answer:
The rate of change is 1 mile per hour per month
Step-by-step explanation:
We are given
initial speed = 3 mph
final speed =6 mph
total number of months =3
now, we can use rate of change formula
we know that
rate of change = ( final speed - initial speed)/(total number of months)
now, we can plug values
and we get
Rate of change is
mph per month
=1 mph per month
