140mtslong?/360 मी. लम्बी एक रेलगाडी, 45 किमी/घंटे की चाल से दौड रही है। 140 मी. लम्बे पुल को पार करने में यह कितना समय लेगी
​

Answer 1

Answer:

Total distance = Distance of bridge + Distance of Train

Total Distance = 140 + 360

Total Distance = 500 m

Speed = 45 km/hr = 45×5/18 m/s = 12.5 m/s

Time = Total Distance/Speed

Time = 500/12.5

Time = 40 s
