3 hr = 180 min. 200 min. is greater.
3 hr = 180 minutes180 + 15 = 195 minutes
.75 hr is the same as 3/4 of hour, so 60 min x 3/4 = 45 min 2 hr is the same to 2 x 60min = 120 min And 45 min + 120 min = 165 min OR simply: 2.75hr x 60min/min = 165min
10 hours and 15 minutes
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)
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
60 min in 1 hr ... SO181÷60 = 3 hr (and 1 min)
3 hr = 180 min. 200 min. is greater.
3 hr = 180 minutes180 + 15 = 195 minutes
3 wks * 7 days/wk * 24 hr/day * 60 min/hr = 30240 min
.75 hr is the same as 3/4 of hour, so 60 min x 3/4 = 45 min 2 hr is the same to 2 x 60min = 120 min And 45 min + 120 min = 165 min OR simply: 2.75hr x 60min/min = 165min

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
45 min/lesson x 3 lessons/wk ÷ 60 min/hr = 2.25 hr/wk
