K/2+9=30 1. Start by getting rid of the number farthest from K
-9 -9 2. The nines cancel out, 30-9=21
K/2 = 21 3. Next, get the 2 away from K
/-2 /-2 4. The 2 cancel out when divided, 21 divided by -2= -10.5
K = -10.5
K=-10.5
Thanks with all of my heart!

1 hour = 10 miles
4.5 hours = 10 x 4.5 = 45 miles.
Kristin:
1 hour = 14 miles
4.5 hours = 14 x 4.5 = 63 miles
Difference in distance = 63 - 45 = 18 miles.
