60 sec = 1 min 60 min = 1 hr 40 sec = 40/60 min = 2/3 min 2 min 40 sec = 22/3 min = 8/3 min → 2 min 40 sec = 8/3 ÷ 60 hr = 8/3 x 1/60 hr = 2/45 hr speed = distance ÷ time = 15/8 mi ÷ (2 min 40 sec) = 13/8 mi ÷ (2/45 hr) = 13/8 x 45/2 mi/h = 585/16 mph = 369/16 mph ≈ 36.5 mph
13 hr 8 min - 4 hr 50 min = 8 hr 18 min
43 minutes.
8 hr 40 min + 1 hr 45 min = 10 hr 25 min
(2 pt/min) * (1 gal / 8 pt) * (60 min/hr) = (2 * 1 * 60 * pt * gal * min) / (8 * min * pt * hr) = 15 gal/hr
It takes 8 hr 11 min taking I-95. If you want to take US 13, it takes 9 hr 3 min. I recommend taking I-95
10:05 --> 10 * 60 min + 5 min = 605 min 08:20 --> 8 * 60 min + 20 min = 500 min 605 min - 500 min = 105 min (= 1 3/4 hr)
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 are 60 minutes in an hour Hence as a fraction 8 minutes is 8/60 Cancel down by '4' 8/60 = 2/15 is the fraction an an hour.
