Problem 26.

Assume it takes 8 minutes to fill a 35.0 gal gasoline tank. (1 U.S. gal = 231 cubic inches)
(a) Calculate the rate at which the tank is filled in gallons per second.
(b) Calculate the rate at which the tank is filled in cubic meters per second.
(c) Determine the time interval, in hours, required to fill a volume at the same rate.

Solution:

The rate of filling is 35galons/8 minutes = 4.375 galons/minutes.

(a) Since 1 minute = 60 seconds then

(b) Since 1 minute = 60 seconds and then

(c) From part (b) - is filled within
