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?

The average time taken is 6 hours 57 minutes.

The time given in the question include:

7 hours 12 minutes; 6 hours 46 minutes, and 6 hours 53 minutes.

To find the average, we need to add them together and then divide by 3. This goes thus:

= (7 hours 12 minutes + 6 hours 46 minutes + 6 hours 53 minutes) / 3

= 6 hours 57 minutes.
