The distance traveled by the center is equal to the distance traveled by the wheel 6.28m is traveled by the center.
Given: A wheel with a radius rolled in a straight line through one complete revolution on a flat horizontal surface.
To Find: How many meters did the center of the wheel travel horizontally from its starting location.
Solution:
consider the figure attached.
radius of wheel 
Horizontal distance traveled by the wheel in one complete revolution
=circumference of the wheel
Hence, the distance traveled by center is equal to the distance traveled by the wheel 6.28m is traveled by the center

Answer:
Bailey family's sprinkler was used for 35 hours and Harris family's sprinkler was used for 20 hours.
Step-by-step explanation:
Set up a system of equations.
Let be "b" the time Bailey family's sprinkler was used and "h" the time Harris family's sprinkler was used.
Then:
You can use the Elimination method. Multiply the first equation by -15, then add both equations and solve for "h":
Substitute 
into an original equation and solve for "b":
Answer:
1.6 Gallons Per Day
Step-by-step explanation:
first you got to do 2/3 which is 0.666666 then i multiply 0.66666 by 2 so it at 20 hours which is 1.333333 then i did 0.666666 and divided it by 10 which is 0.066666then i multiply 0.066... by 4 which is 0.2666666 then i added 0.2666666 and 1.3333333 together and it made 1.6
