Jagan went to another town covering 240km by car moving at 60km/hr. Then he covered 400km by train moving at 100km/hr and the rest 200km he covered by bus moving at 50km/hr.The average speed during the whole journey is:
Total time=240/60+ 400/100 + 200/50=12
Avg speed=(Total distance/Total Time)=(240+400+200)/(12)
840/12=70km/hr
Two trains are travelling in the same direction with speeds of 30km/hr and 58km/hr respectively.A man in the slower train passes the faster train in 18s.Find the length of the faster train.
How many seconds will a 500m long train take to cross a man,walking with a speed of 3km/hr in the direction of moving train if the speed of the train is 63km/hr.
Two trains 132m and 108m in length are running towards each other on parallel lines at the rate of 32km/hr and another at 40km/hr.In what time will they be closer to each other from the moment they meet?
A train 150m long passes a telegraph post in 12s.Find speed of the train.
A train is running at the rate of 40km/h. A man is also going in the same direction parallel to the train at a speed of 25km/hr. If the train crosses the man in 48s find length of the train.
