Let a be the last digit, let b be the second to last digit, and let c be the sum of the last three digits of your 8-digit student id. (example: for 20245347, a = 7, b = 4, and c = 14. for 20191502, a = 2, b = 0, and c = 7) two cars are initially (2.50+c) km apart on a straight road. if the cars are moving toward each other, car 1 with a speed of (5.40+a) m/s and car 2 with a speed of (7.20+b) m/s, how many seconds will it take before the cars meet? round your answer to three significant figures.
