Question
An Express Train leaves Central Station at 10:00 AM traveling at a constant speed of 80 km/h. A Freight Train left the same station an hour earlier at 9:00 AM traveling at 60 km/h in the same direction. At what time will the Express Train catch up to the Freight Train?
Options
- A. 12:00 PM
- B. 1:00 PM
- C. 2:00 PM
- D. 2:30 PM
- E. 3:00 PM
Correct answer
B. 1:00 PM
Explanation
At 10:00 AM, the Freight Train has a 60 km head start. The Express Train is 20 km/h faster (80 - 60 = 20). To close a 60 km gap at 20 km/h takes 3 hours. 10:00 AM + 3 hours = 1:00 PM.
