It takes 15 minutes for Ms. Peter to drive from park to her home
Given :
from her home to the park at an average speed of 30 miles per hour and
returned home along the same route at an average speed of 40 miles per hour
it takes 20 minutes to travel
Convert 20 minutes in to hour (divide by 60)
20 minutes = 1/3 hour
We know that distance = speed x time
From home to park, distance =
So , distance between home and park is 10 miles
Now we calculate the time taken to return from park to home

Time taken is 1/4 hours. Convert it into minutes by multiplying by 60

So it takes 15 minutes for Ms. Peter to drive from park to her home

Answer:
4 pitchers
Step-by-step explanation:
we know that
The volume of a cylinder is equal to

step 1
Find the volume of the cylinder with height 9 inches and radius r
substitute the given values


step 2
Find the volume of the cylinder with height 9 inches and radius 2r
substitute the given values


step 3
we know that
The volume of the cylinder 1 can fill a certain pitcher,
so
The volume of the pitcher is the same that the volume of cylinder 1
therefore
the number of pitchers that can be filled by the second cylinder is equal to divide the volume of the second cylinder by the volume of the first cylinder
