Answer 2

Let's break down the calculations step by step:

2 hours 47 minutes + 5 hours 40 minutes:

First, add the hours: 2 hours + 5 hours = 7 hours. Next, add the minutes: 47 minutes + 40 minutes = 87 minutes. Since there are 60 minutes in an hour, we can convert 87 minutes to 1 hour and 27 minutes. Adding the hours and minutes together: 7 hours + 1 hour = 8 hours, and 27 minutes.

So, 2 hours 47 minutes + 5 hours 40 minutes = 8 hours 27 minutes.

28 hours 10 minutes - 4 hours 10 minutes:

First, subtract the hours: 28 hours - 4 hours = 24 hours. Next, subtract the minutes: 10 minutes - 10 minutes = 0 minutes.

So, 28 hours 10 minutes - 4 hours 10 minutes = 24 hours.

2 hours 49 minutes × 10:

To multiply by 10, simply multiply the hours and minutes separately.

2 hours × 10 = 20 hours. 49 minutes × 10 = 490 minutes.

Since there are 60 minutes in an hour, we can convert 490 minutes to 8 hours and 10 minutes.

So, 2 hours 49 minutes × 10 = 20 hours 8 minutes.

8 hours 27 minutes ÷ 3:

To divide by 3, we divide the hours and minutes separately.

8 hours ÷ 3 = 2 hours and a remainder of 2 hours. 27 minutes ÷ 3 = 9 minutes.

So, 8 hours 27 minutes ÷ 3 = 2 hours 9 minutes.
