But I don't know why or how the above equation is set up. I know that by using their plugging-in method, I can easily plug f=3, m=1, s=60 to have the answer at 1 ft per 1 minute, thus the above formula is the only correct formula, but I would like to understand how to set up an equation so that I can set up problems algebraically when I encounter them during the exam.
Many thanks in advance for all your help.
