Look at the clock.
- How many minutes does it take for the minute hand to move from number 2 to 9?
- If the clock is 40 min slow, what is the correct time?
- If the clock is 30 min fast, what is the correct time?
(a)
Time that the clock takes for the minute hand to move from number 2 to 9

(b)
40 min after 5.10 p.m. = 5.50 p.m.
