Answer:

42:45:22

42 hours : 45 minutes : 22 seconds
or
1 days, 18 hours, 45 minutes, 22 seconds

Solution Steps to Calculate hh:mm:ss *

\[ 42.756 \, hr = 42 \, hr + 0.756 \, hr\]\[ 0.756 \, hr \times \frac{60 \, min}{1 \, hr} = 45.36 \, min\]\[ 45.36 \, min = 45 \, min + 0.36 \, min\]\[ 0.36 \, min \times \frac{60 \, s}{1 \, min} = 21.6 \, s\]\[ 21.6 \, s \approx 22 \, s\]Combining: 42:45:22

* Note that rounding errors can occur for seconds or hundredths of seconds depending on entered data.

How to Convert Decimal Time to hh:mm:ss Format by Total Seconds

Convert 42.756 hours to hh:mm:ss

42.756 hours × 3600 s/hr = 153922 s

Using Long Division with Remainders,

153922 s ÷ 86,400 s/d = 1 d R67522 s
67522 s ÷ 3600 s/hr = 18 hr R2722 s
2722 s ÷ 60 s/min = 45 min R22 s
R22s = 22 s

Combining terms: 1 d, 18 hr, 45 min, 22 s

1 d = 24 hrs so total hours is 42 then,

42:45:22
