Answer 1

C. 6 hours and 40 minutes

Explanation:

To find the average amount of time Ryan slept for those five nights, you need to add up the total time slept and then divide by 5 (the number of nights). Here's the calculation:

Night 1: 6 hours and 20 minutes

Night 2: 5 hours and 50 minutes

Night 3: 7 hours and 5 minutes

Night 4: 6 hours and 47 minutes

Night 5: 7 hours and 18 minutes

Total time = 6 hours 20 minutes + 5 hours 50 minutes + 7 hours 5 minutes + 6 hours 47 minutes + 7 hours 18 minutes = 33 hours 20 minutes

Now, to find the average, divide the total time by 5:

(33 hours 20 minutes) / 5 = 6 hours 40 minutes

So, the average amount of time that Ryan slept for those five nights is 6 hours and 40 minutes. Therefore, the correct answer is:

C. 6 hours and 40 minutes
