To find out how many hours Lily will spend watching this season of Captain's Cove, we first need to determine how much time she spends on each episode.
Last season, Lily watched 30 episodes in a total of 15 hours. We can calculate the time per episode as follows:
\[ \text{Time per episode} = \frac{\text{Total time}}{\text{Number of episodes}} = \frac{15 \text{ hours}}{30 \text{ episodes}} = 0.5 \text{ hours per episode} \]
Now, this season, there will be 24 episodes. To find the total time she will spend watching this season, we multiply the time per episode by the number of episodes:
\[ \text{Total time this season} = \text{Time per episode} \times \text{Number of episodes} = 0.5 \text{ hours per episode} \times 24 \text{ episodes} = 12 \text{ hours} \]
Thus, Lily will spend 12 hours watching this season of Captain's Cove.
