Answer:
0.1875 miles (or 3/16 of a mile)
Step-by-step explanation:
In order to make the math easier for calculating the distance, the values have to be calculated to whole hours.
1.75*2 = 3.5
2.5 * 3 = 7.5, 7.5/2 = 3.75
Now, I divide the whole hours into quarters
3.5/4 = 0.875
3.75/4 = 0.9375
Multiply both values by 3 to get the distance after 3/4 of an hour
0.875 = 2.625
0.9375 = 2.8125
remove the smaller value from the larger value
2.8125 - 2.625 = 0.1875
I might have used a more over-complicated method than what you might have been taught, but it should be just as efficient. Good luck with your assignment!

Step-by-step explanation:
2 root (x-5)=2
Divide each side by 2 (in order to isolate the square root):
Root (x-5) =1
Square both sides to remove the radical sign:
(x-5)=1
Solve:
x=6
To be sure that it is not an extraneous solution, check the solution by replacing the value for the variable in the equation.
2 root (6-5) = 2
The square root of 1 is 1.
2(1)=2
This is correct.
Well the solution is (-3, 3). So I hope that with that you can find which statement is true on your own.
