Best ResponseYou've already chosen the best response.1In that case, you can let \(f(t)=55t\) model the distance covered by the bus and \(g(t)=65t\) model the distance covered by the car. Then you're seeking to solve \(f(t)+g(t)=180\Longrightarrow t=1.5\). In other words, in one hour and thirty minutes, the vehicles will be \(180\) miles apart. There was no need for strange formulas here. :P
