The initial temperature difference of 101-45 = 56 degees declined to 101-55 = 46 degrees in 8 minutes, We can write the exponential equation for the soda's temperature as
... T = 101 -56(46/56)^(t/8) . . . . where t is in minutes
After an additional 10 minutes, we have t=18, so the soda temperature will be
... T = 101 -56(46/56)^(18/8) ≈ 65.0 . . . degrees
(45+20)/(42+45+20+32)
65/139

(X/3) - 8 = 12
X being a number divided by 3. This part in parentheses so you solve it first. Subtract 8 from that and your answer equals 12.
Slope (m) =0
θ =180°
distance (d) =15
ΔX =15
ΔY =0
Constant rate means it is linear so we don't have to worry about fluctuation.
change in y/ change in x=-18-(-25.2)/5-8=2.4 meters per second
