7 hours + 6 hours + 6 hours
=19 hours
12 minutes + 46 minutes + 53 minutes
=111 minutes
=1 hour 51 minutes
19 hours + 1 hour and 51 minutes is 20 hours and 51 minutes. This is the total time.
Average time = total time/number of deliveries
(20 and 51/60) divided by 3
=6.95 hours
= 6 hours and 57 minutes
We need to get x alone, to do that we add 1 to both sides to cancel out the -1 on the right.

all u are doing is adding them up
