Bunuel It may sound as a silly question, but what does what is the time interval between two consecutive buses going in the samedirection mean? Like what does this time (we are calculating)signify?
The phrase "time interval between two consecutive buses going in the same direction" refers to how long you'd wait between seeing one bus and the next while stationary on the road. If you see a bus at 3:00 PM and the interval is "5 minutes," the next bus would pass by at 3:05 PM. It indicates the frequency of buses on that route.
