Atransportation expert measures the amount of traffic on a certain road by recording the number of cars that pass a point on the road every 5 minutes. he starts setting up his equipment shortly before 8 am and manually counts the cars until he gets the electronic monitoring system in place. by exactly 8 am, he has manually counted 43 cars and he starts his equipment. if the electronic equipment records exactly 18 cars passing it every 5 minutes, find a formula to calculate the total amount of cars that have passed that point on the road since the expert started setting up his equipment, at five minute intervals, starting at 8 am. use this formula to figure out what time of day the 871st car will pass by the monitoring system.
