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
1 min = 60 seconds 2 min = 120 seconds 3 min = 180 seconds (3 min + 25 seconds) = (180 seconds + 25 seconds) = 205 seconds
There are 60 minutes in an hour, so we need to multiply the decimal by 60 to get the minutes. 0.89 h * 60 min/h = 54.4 min There are also 60 seconds in a minute, so we need to multiply the decimal by 60 to get the number of seconds. 0.4 min * 60 s/min = 24 s Final answer is 39:54:24 (That is, 39 hours 54 minutes and 24 seconds)
