Best ResponseYou've already chosen the best response.0d = r*t for both Matt and Connor, d = 12 Let r be Connors speed and t be his time Then Matts speed is r+1 because he walks 1 mph faster Matts time is t1 because it takes 1 less hour to complete course set up system of 2 equations: (i) r*t = 12 (ii) (r+1)(t1) = 12 expand (ii) r*t r +t 1 = 12 replace r*t with 12 from (i) 12 r +t 1 =12 solve for r r + t = 1 r = t1 replace r with t1 in (i) t*(t1) = 12 t^2 t 12 = 0 (t4)(t+3) =0 t must be positive for this problem (cant walk 12mi in neg time) t = 4 therefore r = 3 It takes Conner 4 hours to walk 12mi at rate of 3 mph

Best ResponseYou've already chosen the best response.0not sure where you got 5 from if t=5 then r = d/t = 12/5 = 2.4 matt rate would be 3.4 his time would be d/r = 12/3.4 = 3.52 this is more than an hour faster than Conner
