Mathematics (Problem on Trains ট্রেন সংক্রান্ত সমস্যা)

1) A train passes a standing man in 10 seconds. The same train passes a car moving in the opposite direction at 24 km/h in 8 seconds. If the length of the train is 180 meters, what is the speed of the train?

2) The ratio between the speeds of two trains is 3 : 4. The second train runs 800 km in 5 hrs, and speed of
first train is:

3) A train leaves City X at 10 AM and reaches City Y at 2 PM. Another train leaves City Y at 1 PM and reaches City X at 6 PM. At what time do the two trains cross each other?

4) Two trains 85 m and 155 m long, runat the speeds of 62 km/h and 82 km/h respectively, in opposite
directions on parallel tracks. The time which they take to cross each other is

5) Twotrains running in opposite directions cross a man standing on the platform in 25 seconds and 32
seconds respectively and they cross each other in 30 seconds. The ratio of their speedis

6) Two trains are coming from opposite side at 40 km/hrs and 50 km/hrs from the different places 360 km
apart. After how many hours two trains will meet to each other?

7) Two trains A and B,186 m and 200 m long.are running at 64 km/h and 80 km/h, respectively on parallel
tracks. If they are runningin the opposite directions, then how much time(in seconds) will a person
sitting in the first train A take to cross the other train

8) Two trains traveling towards each other are 420 meters apart. If their speeds are 90 km/h and 54 km/h, how much time will they take to meet?

9) A train traveling at a speed of 66 km/h takes 1 minute and 30 seconds to cross a bridge. If the length of the bridge is 990 meters, what is the length of the train?

10) Two trains, 150 meters and 180 meters long respectively, are running on parallel tracks in opposite directions. If they cross each other in 12 seconds, what is the relative speed of the trains?
