divide the distance ( 100 miles) by the speed ( 22 mph) to get the time
100/22 = 4.545454 hours (Round to 4.5 hours ?)
if you need hours and minutes multiply 0.545454 by 60 to get the minutes
4 hours 32.7 ( round to 33) 4 hours and 33 minutes

Answer:
The answer in the procedure
Step-by-step explanation:
Let
x ----> the dog walking hours
y ----> the car washing hours
we know that
The system of linear inequalities is equal to
-----> inequality A
-----> inequality B
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
Two possible combinations of hours are
(10,10) and (0,9)
<em>Verify</em>
For (10,10)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(10,10) is a possible solution
For (0.9)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(0,9) is a possible solution
