4 hr and 21 min

8 hr 40 min + 1 hr 45 min = 10 hr 25 min

10 hours and 15 minutes

Assuming 24 hour times since no am/pm are present (though I would normally expect two digits for the hour, as in 08:15, etc) - 20 hours 30 mins. If the question is from 8:15am to 4:45pm (sounds like a plausible working day) then it is 12 hours less at 8 hr 30 min. 8 15 to 4 45 is: 08:15 to 09:00= 45 mins plus 9:00 to 12:00 = 3 hours plus 12:00 to 24:00 = 12 hours plus 00:00 to 04:00 = 4 hours plus 04:00 to 04:45 = 45 mins Which is 45 min + 3 hr + 12 hr + 4 hr + 45 min = 19 hr 90 min But 90 min = 1 hr 30, so total is 20 hr 30 min

there is 720 min. in 12 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

11:45 am + 1 hr 40 min = 12:45 pm + 40 min = 1:25 pm.

Well, I went to orbitz.com to find your answer.For the flight time: 12 hr, 5 min for to Guam and 11 hr, 5 min to HawaiiFor the actual time (being in the airport, etc.): 18 hr, 35 min to Guam, 22 hr, 35 min

At 60 MPH average, about 8 hr 49 min.

Total transit time is as follows: ORD (Chicago) - IAH (Houston) - 2 hr 40 min (1 hr 12 min - connecting time) IAH (Houston) - LAX (Los Angeles) - 3 hr 39 min (1 hr 28 min - connecting time) LAX (Los Angeles) - SYD (Sydney, Australia) - 14 hr 40 min Total time with connecting times: 23 hr 39 min

At 60 MPH average, about 6 hr 49 min.

36 of anything plus 42 of the same thing results in a total of 78 of them.78 minutes is the same period of time as 1 hour 18 minutes.Or, if you were an old time navigator, it could also be 1 degree 18minutes.

21763874 min ÷ (60 min/hr) ÷ (24 hr/day) = 21763874 min * 1 hr / 60 min * 1 day / 24 hr ≈ 15,113.8 days

60 min = 1 hr ⇒ 330 min = 330 ÷ 60 hr = 51/2 hr = 5.5 hr

5/60 = 1/12

6 hr 49 min Feed back on answer seems pretty legit

3 hr = 180 min. 200 min. is greater.

511 mi / 75 mph = 6.81 hr = 6 hr 49 min

There are 60 min in an hr ... SO60 min x 2½ min/hr = 150 min.

346 (5 hrs X 60 min./hr. =300 min. plus the 46 min. =346 minutes, total).

(270 min) / (60 min/hr) = 4.5 hr

43 minutes.

60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr

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

13 hr 8 min - 4 hr 50 min = 8 hr 18 min
