Answer:
70/3=23.33 minutes/mile. 110/23.33=4.714 miles.
Step-by-step explanation:

1. We assume, that the number 53.55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 53.55 is 100%, so we can write it down as 53.55=100%.
4. We know, that x is 15% of the output value, so we can write it down as x=15%.
5. Now we have two simple equations:
1) 53.55=100%
2) x=15%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
53.55/x=100%/15%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 15% of 53.55
53.55/x=100/15
(53.55/x)*x=(100/15)*x - we multiply both sides of the equation by x
53.55=6.6666666666667*x - we divide both sides of the equation by (6.6666666666667) to get x
53.55/6.6666666666667=x
8.0325=x
x=8.0325
*******
now we have:
15% of 53.55=8.0325.
the total price was 53.55+8.0325=61.5825 the price before the discount
61.5825 - 38 = 23.5825 ~ 23.58
Answer:
Distance between the observer and the red car is 
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =
Let R be the radius and the speed at which the car completes race be w
So,
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes = 
So, 
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=
