Look at the clock.
- How many minutes does it take for the minute hand to move from number 3 to 11?
- If the clock is 15 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 3 to 11
= 40 min
(b)
15 min after 3.15 p.m. = 3.30 p.m.
Correct time if the clock is 15 min slow is 3.30 p.m.
(c)
30 min before 3.15 p.m. = 2.45 p.m.
Correct time if the clock is 30 min fast is 2.45 p.m.
Answer(s): (a) 40 min; (b) 3.30 p.m.; (c) 2.45 p.m.
