Answer:
41 minutes
Explanation:
According to this question;
- Roberto spent 90 minutes doing homework
- Roberto spent 2/3 hour reading. Since 1 hour = 60 minutes
2/3 hour = 2/3 × 60 = 40 minutes.
- Roberto spent 540 seconds making his lunch for the next day. Since, 60 seconds = 1 minute
540 seconds = 540/60
= 9 minutes.
The total amount of time Roberto spent reading and making his lunch is = 40 + 9 = 49 minutes.
Therefore, the amount of time Roberto spent doing his homework than reading and making his lunch is (90 - 49) = 41 minutes.
