Answer:
it is 8
Step-by-step explanation:
<u>Given</u>:
Given that Jasmine rides her bike 9 miles in 50 minutes.
We need to determine the speed per hour.
<u>Time per hour:</u>
The time taken is 50 minutes. We need to convert minutes into hours.
Thus, we have;

Thus, the time taken to cover 9 miles is 
<u>Speed:</u>
The speed can be determined using the formula,

Substituting the values, we have;

Simplifying, we get;



Thus, Jasmine's speed is 10.8 miles per hour.
Answer:
68°
Step-by-step explanation:
Since WX and ZY are parallel, angle W and angle Z should add up to 180°
W + Z = 180°
112° + Z = 180°
Z = 68°
Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.
If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).
Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.
c^2 = a^2 + b^2
where c is the total displacement from the starting point to the end point
a is the distance he walks up north
b is the distance he walks to the west
c^2 = 100^2 + 100^2
c^2 = 10,000 + 10,000
c^2 = 20,000
c = 141.42 meters
Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.
100 meters + 100 meters - 141.42 meters = 53.58 meters
