3. It took the family 330 minutes to travel to Baguio.

4. The teachers had 2 hours and 30 minutes in the meeting.

5. The seminar lasted in 2040 seconds.

Step-by-step explanation:

1 year = 12 months

1 month = 4 weeks

1 week = 7 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

For No. 1:

1 hour = 60 minutes

240 divided by 60 = 4

so the answer for number 1 is 4 hours.

For No. 2:

1 week = 7 days

35 divided by 7 = 5

so the answer for number 2 is 5 weeks.

For No. 3:

Given: 5 1/2 hours

= 5 hours and 30 minutes

1 hour = 60 minutes

60 x 5 = 300

300 + 30 = 330

so the answer for number 3 is 330 minutes.

For No. 4:

Given: 150 minutes

1 hour = 60 minutes

150 divided by 60 = 2.5

.5 means half

half of 1 hour is 30 minutes

so the answer for number 4 is 2 hours and 30 minutes.

For No. 5:

Given: 4 hours and 10 minutes

1 hour = 60 minutes

1 minute = 60 seconds

60 x 4 = 24

24 + 10 = 34

34 x 60 = 2040

so the answer for number 5 is 2040 seconds.
