1 minute has 60sec
3 minutes has 3 times 60sec = 180 seconds
1 hour has 60 min/hr x 60sec/min = 3600 seconds
2 hours has twice that or 7200 seconds
Total of 7200 seconds + 180 seconds = 7380 seconds

Oh, what a lovely question! In 2 hours, there are 120 minutes, and when you add 15 more minutes, you have a total of 135 minutes. Since there are 60 seconds in a minute, you can multiply 135 by 60 to find there are 8,100 seconds in 2 hours and 15 minutes. Just imagine all the beautiful things you can create in that time!
To convert 9435 seconds into hours, minutes, and seconds, you would first divide 9435 by 3600 (the number of seconds in an hour) to get 2 hours. Next, you would take the remaining seconds (2355) and divide by 60 (the number of seconds in a minute) to get 39 minutes. Finally, the remaining seconds would be 15 seconds. Therefore, 9435 seconds is equivalent to 2 hours, 39 minutes, and 15 seconds.
Convert all of the values into seconds, then average them, then convert back to minutes. For example (with value 4 minutes and 30 seconds and value 20 seconds) 4m, 30s- 4*60=240+30=270s 20s would stay as 20s 270s+20s=290s 290/2=145s The average would be 145s or 2m, 25s
2 hours is 120 minutes x 60 seconds per minute = 7200 seconds 14 minutes x 60 seconds per minute = 840 seconds total 8040 seconds.
1 hour = 60 minutes so 2 hours = 2*60 = 120 mintes. Then 2 hours + 54 minutes = 120 + 54 = 174 minutes. 1 minute = 60 seconds so 174 minutes = 174*60 = 10440 seconds.
