        Or have ROMOS do the math for you. Did I miss a step in my set up?

        Quarter of a "minute"?

        Nope, I see it. I put 6 seconds in a minute, not 60

        Edited after actually reading the question correctly :)


        1,100 ft per second.


        15 seconds in a quarter of a minute. 


        1,100 X 15 = ? 


        Do the math

          No quarter of an hour in the question.

          Ugh. For some reason my mind read quarter of an hour. Probably because 1/4 of a minute is not common like 1/4 of an hour.

          I even read it the same way the second time around.
          commented 13 years ago

          15 X 4 = 60.So, a quarter of a minute is 15 seconds.So, 15 X 1,100 =16,500'.
