good day!
i need help and be guided on the right path here, i'm pretty sure i'm lost. im trying to compute for time diffrence for start time and end time manually versus automatic ex. online computation.
start time =08:55 am end time =13:22 pm
for manual computation, i did this.
8-13 =4 hrs 55-22 =33 min
I know that getting the time difference is by subtracting both start time(hour) -end time(hour) and both start time(minutes) -end time(minutes) combine both =4:33 hrs in total manually
I did not *60 or divide 60 because its not over 60.
my problem is when I try computing this online ex:http://www.onlineconversion.com/days_between_advanced.htm http://www.grun1.com/utils/timeDiff.cfm
the total time is: 4:27:00 hrs
is there another computation that needs to be done. if so can you help me. am i wrong
thank you
Count hours and minutes separately, and then use the fact that $1$:$00=0$:$60$.
$13$:$22-08$:$55=(13-8)$:$(22-55)=5$:$(-33)=4$:$27$
