d = rt
where d is distance, r is rate of speed, and t is time.
For both skaters, distance = 1 mile.
Given: Jennie: 1 = 2.5r(t - 6)
Michel: 1 = rt
For Jennie's situation, solving for rate:r = d/t2.5r = 1/(t - 6) // using substitution
r = 1/2.5(t - 6) // divide by 2.5r = 1/(2.5t - 15) // Jennie's rate (in miles/minute)Next, substitute Jennie's rate for Michel's rate and solve for time:t = d/rt = 1/(1/(2.5t - 15)) // using substitutiont = 2.5t - 15 // from here on out, simplify equationt - 2.5t = -15 -1.5t = -15t = 10 //
Michel's time (in minutes)Jennie's time is t -6, therefore:
Jennie took 4 minutes and Michel took 10 minutes.
