4 hr and 21 min
60 min = 1 hr ⇒ 330 min = 330 ÷ 60 hr = 51/2 hr = 5.5 hr
There are 60 min in an hr ... SO60 min x 2½ min/hr = 150 min.
43 minutes.
(270 min) / (60 min/hr) = 4.5 hr
time = distance / speed = 0.25 miles / 200 mph = 0.00125 hr 1 hr = 60 min → 0.00125 hr = 0.00125 × 60 min = 0.075 min 1 min = 60 sec → 0.075 min = 0.075 × 60 sec = 4.5 sec → it takes 4½ seconds to travel 0.25 miles at 200 mph.
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
3.08 hr or 3 hr 5 min.
4 hr and 21 min
21763874 min ÷ (60 min/hr) ÷ (24 hr/day) = 21763874 min * 1 hr / 60 min * 1 day / 24 hr ≈ 15,113.8 days
200 miles going 60 mph will take about 3 hr 20 min.
60 min = 1 hr ⇒ 330 min = 330 ÷ 60 hr = 51/2 hr = 5.5 hr
There are 60 min in an hr ... SO60 min x 2½ min/hr = 150 min.
43 minutes.
About 2 hr 50 min.
(270 min) / (60 min/hr) = 4.5 hr
60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr
