Answer:
The postal carrier can deliver to 130 houses in 2.5 hours. To find out how many hours it will take to deliver to 312 houses at this rate, we need to use the formula:
time = (number of houses) / (rate of delivery)
We know that the rate of delivery is 130 houses per 2.5 hours. To find the time it will take to deliver to 312 houses, we can plug in the values:
time = (312 houses) / (130 houses per 2.5 hours)
time = 312/130 * 2.5 = 2.5 * 2.4 = 6 hours
So it will take 6 hours to deliver to 312 houses at this rate.
