we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?

Slope of the line
(3-(-5)) / (-5-(-1))
8 / -4
-2
Your doing everything correctly
It would take 2.8 hours ((3.5 hours x 2.4 Mph)/3Mph) hours for Max to cover the same route walking 3 mph. This problem can be solved by using the velocity equation which is the velocity is equal a change in position divided by a change of time. The amount of time can be found assuming that Max walks in a constant velocity from the starting point until the finish point of 8.4 miles distance (3.5 hours x 2.4 mph)<span>.</span>
