in 2011 the average marathon time for men was 4 hours and 26 minutes and the average time for women was 4 hours and 52 minutes
what is the average of those two times
to find out the average time , adds the two times and then divide by 2
Adds the hours
(4+4)/2=4 hours
Adds the minutes
(26+52)/2=78/2=39 minutes
therefore
the average time is 4 hours and 39 minutes
