A railway line connects Parnac station with Rougelle station. The distance between these two stations is 150 km. -a train departs from Parnac at 17:10 and stops at Bernouille station at 17:40. Bernern is 60 km from Parnac - He leaves Bernouille twenty minutes later and crosses the Sévillon train station at 18:30. The Sévillon train station is 45 km from Rougelle. He continued his journey at the same speed until Rougelle station. -Another train leaves Rougelle at 17:35 and arrives at Sévillon at 18h. After 10 minutes of waiting he leaves to reach Bernouille at 18:40 and stops 10 minutes. He finally joined Parnac at 19:20. "At what time and how far from Rougelle do the trains intersect?"

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
