Example 1: Nina takes 2 hours 35 minutes to finish her homework. How
many minutes is that?
Answer: Time taken by Nina to complete her homework = 2 hours 35 minutes
We know, 60 minutes = 1 hour.
2 hours 35 minutes = 2 hours + 35 minutes
= 2 x 60 minutes + 35 minutes
= (120 +35) minutes
= 155 minutes
Therefore, Nina takes 155 minutes to complete her homework.
