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?

Step-by-step explanation:

1. Add the hours and minutes separately

2. Calculate the average time

The hours do not divide evenly by 3.

(a) Convert the hours to a multiple of 3.

Subtract 1 h  from the hours and add 60 min to the minutes

Now, the hours are divisible by 3.

(b) Divide by three

Divide the hours and the minutes separately

6 hours 57 minutes

Step-by-step explanation:

1 hour = 60 minutes

On Monday delivery time = 7 hours 12 minutes

Change into minutes, 7 hours 12 minutes = 7×60+12 = 432 minutes

On Wednesday delivery time = 6 hours 46 minutes

Change into minutes, 6 hours 46 minutes  = 6×60+46 = 406 minutes

On Friday delivery time = 6 hours 53 minutes

Change into minutes, 6 hours 53 minutes = 6×60+53 = 413 minutes

To find the average time for a delivery run.

Now change 417 minutes to hour

60 minutes = 1 hour

417 minutes = 6 hours 57 minutes

Hence, the average time for a delivery run is 6 hours 57 minutes
