Answer:
(9/10 mile)/(5/3 hour) = 27/50 miles/hour
Step-by-step explanation:
If you are looking for the speed, then speed = distance/time
speed = (9/10 mile)/(5/3 hour)
speed = 9/10 ÷ 5/3 miles/hour
speed = 9/10 × 3/5 miles/hour
speed = 27/50 miles/hour

Look at the attached figure. We define the unit circle as a circle with center
in the origin (0,0) and radius 1.
Then, we consider a point P on the circumference. We call
the angle between the positive half of the x axis and the radius AP.
We define

As you can see, ACD is a right triangle, and so we have

But since we know that AD is the cosine, AC is the sine, and AP is the radius (which is 1, and remains 1 when squared), we have just found out that

Its 3. Since 2 is a small number, lower than 5, so you round down to 3
2.4 of Fatima model is shading so that is the answer
