Time

8 and 1/2

6:00 + 2:30 = 8:30

or

14:30 - 06:00 = 08:30

eight and a half

8 + 24 + 24 + 9 = 65

There are 10.25+24k where k is an integer.

It is 4 hours and 30 minutes.

50 miles = 60 minutes

50/50 miles = 60/50 minutes

1 mile = 6/5 minutes

12 miles = 12 x 6/5 minutes

12 x 6/5 = 72/5 = 144/10 = 14.4

60 x 0.4 = 24

or

5 miles = 6 minutes = 360 seconds

1 mile = 360/5 = 72 seconds

12 miles = 12 x 72 = 864 seconds

60 x 14 = 840 = 864 - 24

Answer: 14 minutes 24 seconds

three

14:00 - 11:00 = 03:00

2017 - 1921 = 96

1:32 + 47 minutes is 2:19.

132 minutes plus 47 minutes is 179 minutes, which is 2 hours and 59 minutes.

12:45pm is 47 minutes before it. 2:19pm is 47 minutes after it.

over 73

1,772.50 / 24 = 73.8541667

1,772.50 - 20.50 = 1,752 = 24 x 73

73 days 20.50 hours

11:50 + 0:10 = 12:00

0.45 - 0:10 = 0.35

12:00 + 0:35 = 12:35

17:00 - 10:30 = 06:30

1:30 + 5:00 = 6:30

Go back one day to 5:05 AM the previous morning. That's 24 hours. Go back 12 more hours to 5:05 PM the day before that.
