A train leaves Station A at 09:00 and travels at 80 km/h. Another train leaves Station B at 10:00 and travels towards Station A at 100 km/h. The distance between stations is 500 km. At what time will they meet?
- A.12:20
- B.12:30
- C.12:40
- D.13:00
Kunci jawaban & pembahasan
Jawaban: 12:20
By 10:00, first train has traveled 80 km. Remaining distance = 420 km. Combined speed = 180 km/h. Time to meet = 420/180 = 2.333... hours = 2 hours 20 minutes after 10:00, so 12:20.
