Best ResponseYou've already chosen the best response.0287 = (s+4)(3.5) + 3.5s 287 = 3.5s +3.5s + 14 28714 = 7s 273 = 7s 273/7 = s 39 = s

Best ResponseYou've already chosen the best response.0(s+4)(3.5) = s(3.5) + 287

Best ResponseYou've already chosen the best response.0thenDr + Ds = 287 if thats the case 7s +14 = 287 7(s+2) = 287 i still get 39

Best ResponseYou've already chosen the best response.0if sally is not moving, does that change the dynamics of our problem?

Best ResponseYou've already chosen the best response.0yeah cuz then she would have no speed

anonymous

Best ResponseYou've already chosen the best response.0and therefore would have no distance

Best ResponseYou've already chosen the best response.0think of it like this maybe....in one hour, randy if 4 miles farther.....

Best ResponseYou've already chosen the best response.0that wouldnt change the equation for sally's speed though..

Best ResponseYou've already chosen the best response.0they have traveled a distance of 273 miles if they were traveling the same speed right?

Best ResponseYou've already chosen the best response.0no because when we substitute R in for S+4 they arent

Best ResponseYou've already chosen the best response.0randy is 14 miles further than sally at 3.5 hours right?

amistre64

Best ResponseYou've already chosen the best response.0so 287  14 = the distance traveled by Sally in 3.5 hours right? 273 in 3.5 hours?

amistre64

Best ResponseYou've already chosen the best response.0speed equals distance/time
