# Rahim plans to drive from city A to station C, at the speed of 70 km per hour, to catch a train arriving there from B. He must reach C at least 15 minutes before the arrival of the train. The train leaves B, located 500 km south of A, at 8:00 am and travels at a speed of 50 km per hour. It is known that C is located between west and northwest of B, with BC at 600 to AB. Also, C is located between south and southwest of A with AC at 300to AB. The latest time by which Rahim must leave A and still catch the train is closest to
