The boat departed from the pier at 8:45 am and went to the village for 80 minutes.

The boat departed from the pier at 8:45 am and went to the village for 80 minutes. Is it true that the boat arrived in the village at 10:05 am?

First, we need to find out how many minutes are missing from 8:45 to 9:00.

Based on the fact that there are 60 minutes in an hour, we calculate that 15 minutes are not enough before 9:00.

Subtract these 15 minutes from 80:

80 – 15 = 65 minutes. More than an hour left. Let’s expand this number as the sum of one hour and the remaining time:

65 = 60 + 5.

By 9:00 we add 60 minutes, which is 1 hour.

Now we have 10:00 and 5 minutes in reserve. Add 5 minutes to 10:00 to get 10:05.

Conclusion: Yes, that’s right.
