    correct

    s=d/t

    since s is 500 ft/sec in this case, and d is 50 ft, we get

    500 ft/sec = 50 ft/ t

    lets solve for t

    start by multiplying each side by "t" in order to get it out of the denominator

    500 ft/sec * t = 50 ft * t/t

    t/t = 1

    50 * 1 = 50

    so

    500 t feet/sec = 60 ft

    divide both sides by 500 ft/sec and get

    500 t feet/sec / (500 ft/sec) =50 ft / (500 ft/sec)

    500 feet/sec divided by 500 ft/sec equals 1, and 1 times t is just t so

    t=50 ft / (500 ft/sec)

    t= .1 sec

    so we went through that the way that uses the formula and works every time

    but a quick look can give this a "makes sense" check

    if you can go 500 feet in one sec, then it only going to take a tenth as long to go a tenth as far

    so, 500 feet per 1 sec, means 50 feet in a tenth as long, or .1 sec

    makes sense, huh?

    0.1 seconds

    500/1 = 50/0.1

    Kind of like simplifying fractions.
