PART A AND B ARE BOTH ANSWERED AT THE END OF THE QUESTION:)convert her walking speed from mph to feet per hour.
3 times 5,280=15,840 feet---her speed per hour.
15,840/60=264 feet-----her speed per minute
THEREFORE: 5 times 264=1,320 feet----that she walked when you started, or: 1,320/5,280=1/4 of a mile she walked in 5 minutes.

Part A:

60/3= 20

You travel 1 mile every 20 minutes.

So, 5 minutes is 1/4 of 20.

Your friend walked 1/4 of a mile.

Part B:

You already know that your friend was 1/4 mile ahead of you.

She will continue to walk at the same rate.

You will walk:

6/4= 15

1 mile every 15 minutes.

Every 5 minutes, you walk a 1/3 of a mile.

(this is distance walking every 5 minutes)
Friend/ You

1/4 0

2/4 1/3

3/4 2/3

4/4 3/3

4/4= 1 and 3/3

Your friend will have walked 20 minutes before you caught up with her.

I hope this helps!

Midpoint Formula: $(\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})$

So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:

$\frac{-1+x}{2}=0.5\\\\-1+x=1\\\\x=2$
