    This is very simple; we are trying to find how many hours she rode in total today, so our formula is : Miles / miles per hour For example, if she rode 25 miles in the day, going at a constant speed of 12 we would divide 25 by 12 we would find out that she rode 2.1 hours. (2.08, but I estimated)

    That means what you need to do is divide the miles by the mph earlier that day, and then add it up with the later of the day. Miles / mph + Miles / mph = hours

    time = distance / speed

    So, so far we know that our equation is Miles / mph + 24 / 15 = hours

    t = d/t t = 18/12 + 24/15

    I never payed attention to formulas as a kid o.o I always just did it logically in my head.... I would always studder when teacher asked to write out my work because I did it all mentally lol.
