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=
AC = 2 BD
Distance BD = √[(2.5+1)^2 +(3-3)^2]
Distance BD = √(3.5)^2
Distance BD = 3.5
AC = 2 * 3.5 = 7
Answer
d. 7
Answer:
Your answer is 7
Step-by-step explanation:
The two lines are the same length, so set the lengths equal to each other.
5x-3=11-2x
add 2x
7x-3=11
add 3
7x=14
divide by 7
x=2
Then you just plug x in
5(2)-3
multiplication first
10-3
subtraction
7
That is your answer
