60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr
10 hours and 15 minutes
60 min = 1 hr ⇒ 330 min = 330 ÷ 60 hr = 51/2 hr = 5.5 hr
There are 60 min in an hr ... SO60 min x 2½ min/hr = 150 min.
(270 min) / (60 min/hr) = 4.5 hr
60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr
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
10 hours and 15 minutes
(1 mile)/(90 miles/hr) = (0.01111... hr)*(60 min/hr) = 0.66667 min or 40 sec.
60 min = 1 hr ⇒ 330 min = 330 ÷ 60 hr = 51/2 hr = 5.5 hr
21763874 min ÷ (60 min/hr) ÷ (24 hr/day) = 21763874 min * 1 hr / 60 min * 1 day / 24 hr ≈ 15,113.8 days
There are 60 min in an hr ... SO60 min x 2½ min/hr = 150 min.
(270 min) / (60 min/hr) = 4.5 hr
There are 60 minutes in 1 hourTherefore 192 minutes divided by 60 minutes equals 3 hours 2 minutes.
1218 = 1200 + 18. (1200 min)/(60 min/hr) = 20 hr, so 1200 min = 20 hr, then add the 18 minutes, so 20 hr, 18 min or 20:18
60 min in 1 hr ... SO181÷60 = 3 hr (and 1 min)
1 hr = 60 min 10 hr = 600 min
