Answer:
Pete worked for 4 hours.
Step-by-step explanation:

A number that is calculated by adding quantities together and then dividing the total by the number of quantities.
Given that, For the Christmas dance, the dance committee needs three hours of music. Each song is an average of 3.5 minutes.
Converting 3 hours into minutes,
1 hour = 60 minutes
3 hours = 60x3 = 180 minutes
