Answer: 75.143 mph

Step-by-step explanation:
First you need to set up the equation
252=14(s-60)+40

Get rid of the parenthesis by distributing the 14
252=14s-840+40

combine like terms
252=14s-800

rearrange so the variable is on the left then combine like terms again.
-14s= -252-800
-14s= -1052

divide both sides by -14

s= 75.143
