Answer:11 hours
Step-by-step explanation:
you would add all three hours and then divide by 3 but first you would have to convert the minutes into hours so it would be 900/60 which is 15 so then you would do 8+10+15 / 3 which gives you 11
3.1
First, we need to convert 10/100s into a decimal. We can simplify it to 1/10, which is also 0.1.
Then, we add 0.1 to 3 and get our answer: 3.1.
Hope this helped!
Tried a whole bunch of odd sequences:
11 + 13 + 15 = 39
Nope too small.
21 + 23 + 25 = 69
Woah too big!
And after a few more trials found that:
17 + 19 + 21 = 51
Woohoo!
