Erica and Amy started biking in the opposite directions at the same time from the same place. Erica biked at a speed of 6 meters

ipn [44]

Since they are moving in opposite directions, this is the same as Amy staying still and Erica biking at 10 meters per second away from her.

To travel 1km = 1000m at 10 meters per second, you need 1000/10 = 100 seconds.

Answer:

Center: (3,3)

Radius: $2\sqrt{5}$

Step-by-step explanation:

Midpoint and Distance Between two Points

Given two points A(x1,y1) and B(x2,y2), the midpoint M(xm,ym) between A and B has the following coordinates:

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The distance between both points is given by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Point (5,7) is the center of circle A, and point (1,-1) is the center of the circle B. Given both points belong to circle C, the center of C must be the midpoint from A to B:

$\displaystyle x_m=\frac{5+1}{2}=\frac{6}{2}=3$
