Answer:
<h2> 3hours 55 minute</h2>
Step-by-step explanation:
Step one:
Given data
distance= 160miles
velocity = 3/4 miles per minutes
Step two:
Required:
time
we know that velocity is
v=distance/time
times= distance/velocity
time=160/3/4
time= 160*4/3
time=640/3
time=213.33333minuts
Time= 3hours 55 minute
Using the given center and point at the circumference, the equation of the circles are:
- a)

- b)

- c)

<h3>
What is the equation of a circle?</h3>
- The equation of a circle of radius r and center
is given by:

Item a:
- Center C(5,2), hence
.
The point at the circumference is A(11,10), hence:



Hence:

Item b:
- Center C(-2,-5), hence
.
The point at the circumference is A(3,-17), hence:



Hence:

Item c:
- Center C(5,-1), hence
.
The point at the circumference is A(-2,-5), hence:



Hence:
