Answer:

- 978.6 gallons per hour

Step-by-step explanation:

Given that :

Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal

Time during which change occurred : 2:00 pm to 4:00 pm

Average change per hour : [Change in gallon of gasoline / time interval (hour)]

Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons

Time interval = 4:00 pm - 2:00 pm = 2 hours

Hence, Average change per hour :

-1957.2 / 2

= - 978.6 gallons per hour
