Answer:
3/4
Step-by-step explanation:
Jessica shaded 6/8 of the circle. That fraction can be reduced by removing a factor of 2 from numerator and denominator. The reduced fraction is 3/4.
At 9 a.m., Jessica started riding on the Red Mountain Parkway at the 40-mile marker.

Answer:
See below
Step-by-step explanation:
Start time = 9 A.M.
<h3>Jessica</h3>- Start point- 40 miles
- Speed - 30 mph
<u>Equation</u>:
- y = 40 + 30x
- Start point- 10 miles
- Speed - 40 mph
<u>Equation</u>:
- y = 10 + 40x
<u>Note</u>. <em>There is no graph but see the attached. It should be similar graph for this case</em>
The will meet after 3 hours at 130 miles mark
<u>Solving the system of equations we get:</u>
- 40+30x = 10 + 40x
- 10x = 30
- x = 3
And y is:
- y = 40+3*30 = 130
(3, 130) is the intersection of lines
Since it takes 3 hours for Jessica and Kate, it happens at 12 A.M.
