I'm struggling with the right formula as IE120 PERFORMANCE .xls need to have the time of a flight, flying at rate of 1,500" (FPM) Foot Per Minute up to the 10,000". So, I've tried to divide the 10,000 by the 1,500 and have set'ed the other cell with the time format but the result is wrong.

My problems are on the "Sheet 2" of the attached file.

Thank You.
