Wat is die tyd op die volgende horlosies? a. [Clock image] b. [Clock image] c. Hoeveel tyd het verloop vanaf horlosie a tot horlosie b?

The short (hour) hand is past the 2 but has not reached the 3. So the hour is 2.

The long (minute) hand is pointing at the 3. Each number on the clock represents 5 minutes. So, $3 \times 5 = 15$ minutes.

The time on clock a is $\boxed{\text{2:15}}$.

The short (hour) hand is past the 8 but has not reached the 9. So the hour is 8.

The long (minute) hand is pointing at the 8. Each number on the clock represents 5 minutes. So, $8 \times 5 = 40$ minutes.

The time on clock b is $\boxed{\text{8:40}}$.

Start time (clock a): 2:15
End time (clock b): 8:40

Subtract the start time from the end time.
Hours elapsed: $8 - 2 = 6$ hours
Minutes elapsed: $40 - 15 = 25$ minutes

The time elapsed is $\boxed{\text{6 hours and 25 minutes}}$.
