#2h + 48 min#

#2h + 8/10 h = #

#2h + 8/10 * 60min#

#2# hours and #48# minutes and #0# seconds

Given: #2.8 #hours

#2.8 #hours is #2# hours and #0.8# of an hour.

Since there are 60 minutes in an hour:

#(0.8 cancel(hr))/1 xx (60 min.)/(1 cancel(hr)) = 48 # min.

When multiplying #0.8 xx 60# we did not get any decimal. This means there aren't any seconds.

#2.8 # hours = #2# hours and #48# minutes and #0# seconds
