Look at the clock.
- How many minutes does it take for the minute hand to move from number 2 to 4?
- If the clock is 20 min slow, what is the correct time?
- If the clock is 45 min fast, what is the correct time?
(a)
Time that the clock takes for the minute hand to move from number 2 to 4
= 10 min
(b)
20 min after 5.10 p.m. = 5.30 p.m.
Correct time if the clock is 20 min slow is 5.30 p.m.
(c)
45 min before 5.10 p.m. = 4.25 p.m.
Correct time if the clock is 45 min fast is 4.25 p.m.
Answer(s): (a) 10 min; (b) 5.30 p.m.; (c) 4.25 p.m.
