1 min = 60 sec 30 min = 1800 sec
It is 100*(30 min/5 hours) = 100*(30 min/300 min) = 100*30/300 = 10%
14 min + 3 min 30 sec _______________ 17 min 30 sec
1 hr = 60 min½ hr = 30 min(9 x 60) + 30 = 540 + 30 = 570 min
30 min
30 min/180 hours = 30 min/(180*60) min = 30/(180*60) = 1/36030 min/180 hours = 30 min/(180*60) min = 30/(180*60) = 1/36030 min/180 hours = 30 min/(180*60) min = 30/(180*60) = 1/36030 min/180 hours = 30 min/(180*60) min = 30/(180*60) = 1/360
4 hr 30 min ÷ 3 = 1 hr 30 min Either work directly, remembering 1 hr = 60 mins: 4 hr ÷ 3 = 1 hr remainder 1 hr 1 hr + 30 min = 60 min + 30 min = 90 min 90 min ÷ 3 = 30 min ⇒ 1 hr 30 min Or, convert to minutes, do the calculation and convert back: 1 hr = 60 min ⇒ 4 hr 30 min = 4 x 60 min + 30 min = 270 min 270 min ÷ 3 = 90 min 60 min = 1 hr ⇒ 90 min = 90 ÷ 60 hr = 1 hr 30 min Alternatively working in hours: 30 min = 30 ÷ 60 hr = 0.5 hr ⇒ 4 hr 30 min = 4 hr + 0.5 hr = 4.5 hr 4.5 hr ÷ 3 = 1.5 hr = 1 hr + 0.5 hr = 1 hr + 0.5 x 60 min = 1 hr 30 min
you cant ,will you can but not in only 30 min
1 min = 60 sec 30 min = 1800 sec
It is 100*(30 min/5 hours) = 100*(30 min/300 min) = 100*30/300 = 10%
14 min + 3 min 30 sec _______________ 17 min 30 sec
