1 min = 60 s 1 hr = 60 min So 1 hr = 3600 s 5hr = 18,000 s and 30 min = 1800 s. Then 5 hr and 30 min = 19,800 seconds.
1 mi / 45 MPH * 60 min/hr * 60 sec/min = 80 seconds.
8 hr 40 min + 1 hr 45 min = 10 hr 25 min
60 days * (24 hr / day) * (60 min / hr) * (60 sec / min) = 5,184,000 sec
1 hr = 60 min 60 min * 24 hr = 1440 mins in a day 1 min = 60 seconds 60 seconds * 1440 mins = 86400 seconds in a day
3 hours, 35 minutes, and 45 seconds plus 1 hour, 45 minutes and 30 seconds is 5 hours, 21 minutes, and 15 seconds.
0.1 hr * (60 min / 1 hr) * (60 s / 1 min) = 360 seconds
1 min = 60 s 1 hr = 60 min So 1 hr = 3600 s 5hr = 18,000 s and 30 min = 1800 s. Then 5 hr and 30 min = 19,800 seconds.
1 mi / 45 MPH * 60 min/hr * 60 sec/min = 80 seconds.
8 hr 40 min + 1 hr 45 min = 10 hr 25 min
60 days * (24 hr / day) * (60 min / hr) * (60 sec / min) = 5,184,000 sec
1 hr = 60 min 60 min * 24 hr = 1440 mins in a day 1 min = 60 seconds 60 seconds * 1440 mins = 86400 seconds in a day
1 hour = (60min/hr x 60sec/min) = 3,600 seconds 2 hours = (2hr x 3,600sec/hr) = 7,200 seconds
A minute is 60 seconds, so 45 minutes is 45 x 60 = 2700 seconds An hour is 60 minutes, three hours is 180 minutes but each minute is 60 seconds, so 180 minutes is 180 x 60 = 10800 seconds. Adding the two we get 10800 + 2700 = 13500 seconds
(500 yr) x (365.24 day/yr) x (24 hr/da) x (60 min/hr) x (60 sec/min) = 15,778,368,000 seconds(rounded)
.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
many hours is 7am-245pm is : 7 hr 45 min
