In a queue

There are cars and trucks in a queue in front of a toll gate. A truck is three times longer than a car. Calculate how many cars are in the queue ahead of the car that has just arrived, given that one of them is a truck, which accounts for one eighth of the total queue length ahead of the newly arrived car.

Final Answer:

x =  21

Step-by-step explanation:

n = 3a   L  = x a + n  n = L/8   n = (x a+n)/8  3a = (x a+3a)/8  3=(x+3)/8  x=21
