At its plant in Florida, Just D Fruits trucks deliver oranges at the rate of 10,700 kg per hour, from 7 a.m. to 7 p.m.

The plant processes its oranges as soon as the first truck arrives at 7 am, at the rate of 6,450 kg per hour. Processing continues until all deliveries for the day have been processed.

Estimate how many hours are needed to complete the processing of a day's deliveries, ie. the number of hours between 7 am and the time at which the oranges delivered by the last truck will have been processed. For example, if you estimate that the transformation will end at 3:00 AM, you would enter 20.0.

Round the final answer to one decimal (if you got 20.25 hours, you would enter 20.3 and don't convert the 0.25 hours into minutes).
