0. We need to find the time the download finishes.

2. Solution Steps

First, we calculate the download time in seconds.
time=sizespeedtime = \frac{size}{speed}
time=1440 MB1.6 MB/s=900 stime = \frac{1440 \text{ MB}}{1.6 \text{ MB/s}} = 900 \text{ s}
Now we convert the download time to minutes:
900 s=90060 min=15 min900 \text{ s} = \frac{900}{60} \text{ min} = 15 \text{ min}
The download starts at 18:00 and takes 15 minutes. Therefore, the download finishes at 18:
1
5.

3. Final Answer
