6:30pm = 18:30 on 24-hour clock then 18:30 minus 08:30 = 10:00 Answer: ten hours
100+ 08
It is not clear why 08 has a preceding 0: is it meant to be 0.8 or .08? Also, what is meant by "g mL" after 08: is it meant to be just mL or g/mL? "g mL" is not a sensible measurement unit.
.8 = 10 times .08 . .08 is one-tenth of .8 .
Assuming 24 hour times since no am/pm are present (though I would normally expect two digits for the hour, as in 08:15, etc) - 20 hours 30 mins. If the question is from 8:15am to 4:45pm (sounds like a plausible working day) then it is 12 hours less at 8 hr 30 min. 8 15 to 4 45 is: 08:15 to 09:00= 45 mins plus 9:00 to 12:00 = 3 hours plus 12:00 to 24:00 = 12 hours plus 00:00 to 04:00 = 4 hours plus 04:00 to 04:45 = 45 mins Which is 45 min + 3 hr + 12 hr + 4 hr + 45 min = 19 hr 90 min But 90 min = 1 hr 30, so total is 20 hr 30 min
08 - 10 hours
eight 16:00 - 08:00 = 08:00
Aprox 3 to 4 hours
8 hours 40 minutes 16:00 - 07:20 = 08:40
8 hours 30 minutes 16:30 - 08:00 = 08:30 or 4 (8 to 12) + 4.5 (12 to 4.5) = 8.5
4 hours 23 minutes 0:15 + 4:00 + 0:08 = 4:23 = 12:08 - 07:45 unless 12 hours later then 16:23
Three and a half11:30 - 08:00 = 3:30
three hours forty minutes 12:10 - 08:30 = 03:40 unless 12 hours later then 15:40

six and a half 14:30 - 08:00 = 06:30
eight and a half 22:00 - 13:30 = 08:30
