The distance between station A and B is 148 km. From station A to station B left an express train which proceeded with 80 km/h and at the same time from station B towards station A left a goods train with 36 km/h. We know that before the two trains meet at station C the express train drove for 10min and the goods train - 5min. Find: a) The distance between station C and station B b) What time the goods train left station B if the meeting with the express train at station C was at 12 o’clock?
