Time conversion question?

you divide each by 60, you will get the answer

1. 4 hours 50 minutes
2. 9 hours 48 minutes
3. 11 hours 55 minutes
4. 15 hours 10 minutes

1. 4 hours and 50 min
2. 9 hours and 28 min
3. 11 hours and 55 min
4. 15 hours and 10 min

1 hour = 60 minutes
1 minute = 1/60 hour

1)
290 minutes
= 290/60 hours
= 4 50/60 hours
= 4 5/6 hours

2)
588 minutes
= 588/60 hours
= 9 48/60 hours
= 9 4/5 hours

3)
715 minutes
= 715/60 hours
= 11 55/60 hours
= 11 11/12 hours

4)
910 minutes
= 910/60 hours
= 15 10/60 hours
= 15 1/6 hours

I'll give the answer but I'll also tell you how to do it.

290 minutes:
There are 60 minutes in one hour, so divide 290 minutes by 60 minutes to know how many hours equal 290 minutes. This gives 290/60=4.833333333333. So we know it's 4 hours and 0.8333333333 of an hour but we want the minutes and not a percentage of the hour. The remaining minutes of the incomplete hour are 290 minutes minus the minutes in the complete 4 hours. This gives 290-4*60 = 290-240 = 50 minutes.
So the answer to the first question is 4 hours and 50 minutes.

588 minutes:
588/60=9.8
588-9*60=588-540=48
588 minutes = 9 hours and 48 minutes

715 minutes:
715/60=11.916666666666666666666666666667
715-11*60=715-660=55
715 minutes = 11 hours and 55 minutes

910 minutes:
910/60=15.166666666666666666666666666667
910-15*60=910-900=10
910 minutes = 15 hours and 10 minutes

60 minutes = 1 hour

290/60 = 4 rem 50
290 minutes = 4 hours 50 minutes
-----
588/60 = 9 rem 48
588 minutes = 9 hours 48 minutes

etc.

60 minutes = 1 hour

= 290/60

290 minutes = 4 hours 50 minutes

Ans. 290 minutes = 4 hours and 50 minutes

1) 4.83... hours or 4hr and ~48min

2) 9.8 hours or 9hr and ~48min

3) 11.916hours or 11hr 54min and 9sec about that

4) 15.16..hours or 15hr 9min and 36sec
