Explanation / Answer

If if takes you 50 seconds to go up 3 flights of stairs (from the first to the fourth), you can find the rate at which you climb up one floor (how long it took you) divided by (how many flights you went up)=50 seconds/3 flights= 16.67 seconds per flight.  You can then multiply that by by how many flights you have to go up (7) which will give you the total time that it will take you.  so 16.67 sec/floor times 7 floors = 116.67 seconds.
