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.
0.25 hour = 15 minutes 1 minute = 60 seconds therefore 15 x 60 = 900 seconds.
1 hour 15 minutes is 4,500 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
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.
It is 900 seconds. It is one quarter of an hour.
