3 hours and 57 minutes = 14220 seconds3 hours:3 hours * 60 minutes/1 hour * 60 seconds/1minute = 10800 seconds57 minutes:57 minutes*60 seconds/1minute=3420 secondsthus;3 hours and 57 minutes = 10800 seconds + 3420 seconds= 14220 seconds
1 min 57 secondsHere's how.Convert to Seconds3 Min & 54 Sec = 3 X 60 + 54 = 234 SecDivide234 / 2 = 117 SecRe-convert to minutes and seconds.117 Sec = 1 Min & 57 SecORBorrow 1 minute to add to the Seconds.3 Min & 54 Sec = 2 Min & (60 + 54) Sec = 2 Min & 114 SecDivide by 2 = 1 Min & 57 Sec
one way to look at itthere are 60 seconds in 1 minute.1 minute = 60 seconds2 minutes = 120 seconds3 minutes = 180 seconds4 minutes = 240 secondsso 221 seconds is between 180 seconds and 240 seconds so 221 seconds is equal or greater to 3 minutes and less than 4 minutesso therefore the answer is 3 minutes plus some secondsif you take 180 from 221 = 41 seconds then the total time is 3 minutes and 41 seconds.answer: 3 minutes and 41 secondsto check 3 minutes is 180 seconds.. then add 41 to 180 = 221
The average constant speed of the object between 2 and 5 seconds is the total distance covered divided by the time elapsed. If you have the distance covered during this time interval, divide it by 3 seconds (5s - 2s) to get the average constant speed.
There are 4800 seconds in 2/3 of 2 hours
1000 seconds is 16 2/3 minutes
3 minutes 2 seconds
The best male 400 hurdlers run about 2 seconds slower and the women run about 3. The average difference for an efficient hurdler is about 5 seconds for guys and 7 seconds for girls
1 min = 60 seconds 2 min = 120 seconds 3 min = 180 seconds (3 min + 25 seconds) = (180 seconds + 25 seconds) = 205 seconds
3600 seconds/hr = 12600 seconds/(3 1/2 hrs)
3 minutes and 20 seconds
1800 seconds/2 hours = 1800 seconds/2*3600 seconds = 1800/(2*3600) = 1/4
