Arithmetic Grade Four

Lesson One hundred and forty-nine: TIME

You can also convert seconds to minutes and seconds. 


    SIMPLIFY: 211 seconds

    SOLUTION: Divide 211 by 60. 211/60=3 r31

    ANSWER: 3:31
If you have enough seconds you can even get hours out of the seconds. Remember that 1 hour equals 60 minutes times 60 seconds. 


    1 hr = 60 min x 60 sec = 3600 seconds
For instance: 

       Simplify: 4000 seconds

       Solution:

          1) divide 4000 by 3600.  4000/3600 = 1 r 400
          2) divide remainder by 60. 400/60=6 r40

       ANSWER: 1:06:40
