    Here is the formula for speed: \(speed = \dfrac{distance}{time} \) we can abbreviate is as: \(s = \dfrac{d}{t} \) Your question is how many minutes it takes, so you are looking for time. We can solve our equation for t, time. \(s = \dfrac{d}{t} \) \(st = d\) \(t = \dfrac{d}{s} \) The time is the distance divided by the speed. Now plug in the known amounts your problem gives you. \(t = \dfrac{d}{s} \) \(t = \dfrac{240~miles}{45~mph} \) \(t = 5.3333... ~hours\) Now you need to convert from hours to minutes. An hour is 60 minutes. Since an hour is larger than a minute, in the same amount of time there are more minutes than hours. When you go from hours to minutes, the number will become larger. That means you multiply hours by 60 to get minutes. \(5.333... ~hours \times 60 ~\dfrac{minutes}{hour} = 320~minutes\)
