Answer: 6 hours or 360 minutes
Step-by-step explanation:
First find out how long it takes to deliver to one house.
Convert hours to minutes.
2.5 x 60 = 150 minutes total
Divide to find the time per house
150 minutes / 130 houses = 1.15 minutes per house
Now multiply this rate by the number of houses (312).
312 x 1.15 = 360 minutes
If you want it in hours then divide by 60.
360/60 = 6 hours.
They practiced 35 minutes longer on the second day.
Wouldn't it be 72 72/24=3 72/18=4 72/12=6 72/6=12
