A will represent Anna. k will represent Kylie.

7a+7k=231
a=9+k

Substitute for a
7(9+k)+7k=231
63+7k+7k=231
14k=168
k=12

Then plug in the k value
a=9+12
a=21

Final answer: Anna=21 mph, Kylie= 12 mph

What is the exact distance from (−4, −2) to (4, 6)?
Gekata [30.6K]
The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(6--2)^2+(4--4)^2

d^2=8^2+8^2

d^2=64+64

d^2=128

d=√128 units
