Hey there! The answer is:
180 minutes
Explanation:
There are 60 minutes in 1 hour. We know Colin typed his research paper for 3 hours. This means we can multiply 60 minutes by 3 hours and that will give us the number of minutes he spent researching his paper.
60 x 3 = 180
This means Colin typed his research paper for 180 minutes. I hope this answer helped you out, have an amazing day :)
