Last week, your delivery runs took 7 hours 12 minutes on monday, 6 hours 46 minutes on wednesday, and 6 hours 53 minutes on friday. what was your average time for a delivery run? 6 hours 46 minutes 6 hours 53 minutes 6 hours 57 minutes 6 hours 59 minutes 7 hours 10 minutes

6 hours 57 minutes

Step-by-step explanation:

To find the average, we add up all the numbers and then divide by the toal number of numbers

Add them up

7 hours 12 minutes on Monday,

6 hours 46 minutes on Wednesday,

6 hours 53 minutes on Friday

19 hours  111 minutes

But there are 60 minutes in 1 hour, so we subtract 60 minutes and add 1 hour

19 hours  111 minutes

+ 1 hour  - 60 minutes

20 hours  51 minutes

We added 3 terms together so we divide by 3

20 /3 =  6 2/3 hours

51/3 =  17 minutes

But 2/3 hours needs to be changed to minutes

2/3 * 60 = 40 minutes

6 2/3 hours = 6 hours 40 minutes  

Add the hours and minutes together

6 hours 40 minutes

             17 minutes

6 hours   57 minutes
