Question

What is the sum of 7 hours and 54 minutes and 9 hours and 22 minutes?

Answer 1

Step-by-step explanation:

9 + 7 = 16 hours

60 minutes make one hour, and there are only 54 minutes as told

You need 6 more minutes to add to the original 54 minutes to make a complete hour, and 22 - 6 = 16.

In total, the sum is 17 hours and 16 minutes

Answer 2

The sum of 7 hours and 54 minutes and 9 hours and 22 minutes is 17 hours and 16 minutes. This involves adding the hours together and the minutes together, then simplifying the minutes to hours where needed.

Step-by-step explanation:

The student asked for the sum of 7 hours and 54 minutes and 9 hours and 22 minutes. To find the total time, you need to add the hours to hours and the minutes to minutes separately and then simplify the time if necessary.

Step 1: Add the Hours

7 hours + 9 hours = 16 hours

Step 2: Add the Minutes

54 minutes + 22 minutes = 76 minutes

Step 3: Simplify the Minutes

Since there are 60 minutes in an hour, we can convert 76 minutes into hours and minutes.

76 minutes = 1 hour and 16 minutes (because 76 - 60 = 16)

Step 4: Combine the Hours and Minutes

Add the converted time from step 3 to the total hours from step 1.

16 hours + 1 hour = 17 hours

We already have 16 minutes left over from the 76 minutes.

The total sum is 17 hours and 16 minutes.
