1. To add or subtract time, we need to convert the time into a common format. Let's convert the given times into hours and minutes:

a) 21 15 = 21 hours 15 minutes b) 13 05 = 13 hours 5 minutes c) 07 15 (Wednesday) - 20 35 (Tuesday) = (7 hours 15 minutes) - (20 hours 35 minutes)

To subtract the times, we need to borrow 1 hour from the Wednesday time, which becomes 6 hours 75 minutes. Now we can subtract the two times:

6 hours 75 minutes - 20 hours 35 minutes = -14 hours 40 minutes

So the result is -14 hours 40 minutes.

d) 14 35 = 14 hours 35 minutes e) 04 00 (Monday) - 17 55 (Sunday) = (4 hours 0 minutes) - (17 hours 55 minutes)

To subtract the times, we need to borrow 1 day from the Monday time, which becomes 3 hours 24 minutes. Now we can subtract the two times:

3 hours 24 minutes - 17 hours 55 minutes = -14 hours 31 minutes

So the result is -14 hours 31 minutes.

2. Let's convert the given times from 12-hour clock to 24-hour clock:

a) 2:00 am = 02:00 b) 10:55 = 10:55 c) 12:00 pm = 12:00 d) 12:30 pm = 12:30 e) 2:45 pm = 14:45 f) 8:05 pm = 20:05 g) 23:59 = 23:59 h) 12:00 am = 00:00 i) 00:01 = 00:01

Q2) Here is part of a bus timetable:

a) To calculate the time it takes for the bus to get from the bus station to the airport, we need the departure time and arrival time. However, the timetable is not provided, so we cannot determine the exact duration.

b) Chris has a flight at 14:05 and needs to check in 2 hours before the flight. To find the latest time Chris can take a bus from the City Hall to be at the airport on time, we subtract 2 hours from the flight time:

14:05 - 2 hours = 12:05

So the latest time Chris can take a bus from the City Hall is 12:05.
