There are 240, 15 second periods in one hour.
there are 60 seconds in one minute; 3600 seconds in one hour at 1 hr 15 minutes that is 3600 + 15x60 = 4500 seconds
A quarter hour = 15 minutes = 15*60 = 900 seconds.
0.25 hour = 15 minutes 1 minute = 60 seconds therefore 15 x 60 = 900 seconds.
5475 seconds is 1 hour 31 minutes and 15 seconds.
There are 3.6 x 10^15 femtoseconds in an hour. This can be calculated by converting hours to seconds (1 hour = 3,600 seconds) and then converting seconds to femtoseconds (1 second = 1 x 10^15 femtoseconds). Therefore, 1 hour is equal to 3.6 x 10^15 femtoseconds.
there are 60 seconds in one minute; 3600 seconds in one hour at 1 hr 15 minutes that is 3600 + 15x60 = 4500 seconds
A quarter hour = 15 minutes = 15*60 = 900 seconds.
1 hour 15 minutes is 4,500 seconds.
1 hour 15 minutes is 4,500 seconds.
0.25 hour = 15 minutes 1 minute = 60 seconds therefore 15 x 60 = 900 seconds.
1 hour = 3600 seconds which means that 1 second = 1/3600 hour Hence 15 seconds = 15/3600 hour = 5/1200 = 1/240 hour
There are 900 seconds in 15 minutes. (15 minutes is a quarter of an hour) You find this out by multiplying 60 (seconds in a minutes) by 15 (minutes).....HOPE THIS HELPED! :)
3 hours = 10800 seconds there the answer is 10815 seconds.
5475 seconds is 1 hour 31 minutes and 15 seconds.
15 seconds x 1 hour/3600 seconds
It is 900 seconds. It is one quarter of an hour.
To convert 15 seconds to hours, you would divide by 3600 (the number of seconds in an hour). So, 15 seconds is equal to 15/3600 = 0.00417 hours.
