Soal SMA · Soal cerita · Kesulitan 3/5
A train leaves Station A at 8:00 AM traveling at 60 km/h. Another train leaves Station B, 300 km away, at 9:00 AM traveling towards Station A at 90 km/h. At what time will they meet?
- A.10:00 AM
- B.10:30 AM
- C.11:00 AM
- D.11:30 AM
Kunci jawaban & pembahasan
Jawaban: 11:00 AM
By 9:00 AM, the first train has traveled 60 km, leaving 240 km between them. Their combined speed is 150 km/h, so they meet after 240/150 = 1.6 hours, i.e., 1 hour 36 minutes after 9:00 AM, which is 10:36 AM. However, none of the options match 10:36. The closest is 11:00 AM? That's incorrect. Let's recalc: 240/150 = 1.6 hours = 1 hour 36 min. 9:00 + 1:36 = 10:36. Not in options. So this question is flawed. Discard.
