A postal carrier can

deliver to 130 houses in a 2.5

hour period. At this rate,

how many hours will it take to

deliver to 312 houses?

I just need to know the rate for my homework answer.

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.
