It takes you 31 seconds to walk from the first (ground) floor of a building to the third floor. How long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height)?

Step-by-step explanation:

If it takes you 31 seconds to go up 3 floors then it would take you 62 second because half of 6 is 3 and the problem tells you how long it takes to go up 3 floors. So to get 6 floors just double 31 to 62. So it takes 62 second or 1 minute 2 seconds.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
