Unformatted text preview: A car moving with initial velocity at 5 mph accelerates at the rate of a t ( ) = 2.4 t mph per second for 8 seconds. a) How fast is the car going when the 8 seconds are up? b) How far did the car travel during those 8 seconds? Example 4 From 1970 to 1980, the rate of potato consumption in a particular country was C t ( ) = 2.2 + 1.1 t millions of bushels per year, with t being years since the beginning of 1970. How many bushels were consumed from the beginning of 1972 to the end of 1973 Example 5 A pump connected to a generator operates at a varying rate, depending on how much power is being drawn from the generator to operate other machinery. The rate (gallons per minute) at which the pump operates is recorded at 5minute intervals for one hour as shown in the table below. How many gallons were pumped during that hour? Pumping Rate Table Time (min) Rate(gal/min) 0 58 5 60 10 65 15 64 20 58 25 57 30 55 35 55 40 59 45 60 50 60 55 63 60 63...
