    This one actually stumped me pretty hard. I feel like I could just multiply the minutes to the hours.. but Idk, I'm really bad at math, I'm 18 doing freshman math because I couldnt ever bother to come to school, but I'm trying now so I'm ready to learn it, any help would be appreciated really. :)

    these problems don't appear at all at higher level math courses, so I forgot how to do them

    One dumb way to work this problem is like this : Time = \(\dfrac{\text{Distance}}{\text{Speed}}\) = \(\dfrac{\text{125 miles}}{\text{65 miles/hour}}\) = \(\text{1.92 hours}\)

    multiply that by 60 to get the time in minutes

    I think inquisitiveness is the foremost of all the virtues for a student to have, keep it up! :)

    and the miles label gets canceled out leaving with hours. so 1.92 hours -> approx. 2 hours.
