In a bike race, a rider covers a 5-mi flat stretch of road at a speed of s mi/h. She then doubles her speed down a hill 1 mi long. Finally, she reduces her downhill speed by 12 mi/h as she rides the last 3 mi of the race. What function gives the time t it takes for the rider to finish the race in terms of s.

Time = distance divided by speed t=ds t1=5x t2=12x t3=12x−12 The required expression is: T(total)=5x+12x+12x−12
