First convert days into hours. 1 days is equal to 24 hours so 3 days time 24 hours/day is equals to 72 hours. Then convert hours to minutes. There are 60 minutes an hour so multiply 72 hours to 60 minutes. Then you will get 4320.
So 3 days is equals to 4320 minutes or 72 hours.

There are 11,400 seconds in 3 hours and 10 minutes. To solve, convert to minutes and then convert to seconds: 1 hour = 60 minutes 1 minute = 60 seconds ⇒ 3 hr 10 min = 3 x 60 min + 10 min = 190 min = 190 x 60 sec = 11400 seconds
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
The answer depends on what min-1 is measuring, but is likely to be 1 min-1 = 1 rpm.
