Best ResponseYou've already chosen the best response.2for the first problem, after 3 hrs they are 18 miles apart. That means they are separating at 6 mph , right? the speed of chris + speed of brother = 6 c+(c1)=6 (chris runs faster than his bro) 2c1=6 2c=7 c= 3.5 his bro 2.5 mph (not much of a run)
