The rational function V (t) = 390t t +4 models the velocity, V (t), in miles per hour, of a dragster t seconds since it starts its quarter-mile run. The integral of the velocity function from time t = a to time t = b, gives the total distance traveled by the dragster through the time interval a to b. If the driver changes the dragster's velocity function from its current function to V (t) = = 391t t+4 what is the difference in the distance covered in the first 5 seconds of the dragster's run? Round to 2 decimal places. miles
