Bank Preparation Bank Math +১ more A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds. The speed of the second train is _____ ক 48 km/hr 1 54 km/hr 2 82 km/hr 3 66 km/hr সঠিক উত্তর 2 (82 km/hr) ব্যাখ্যা: Solution: Distance covered = (108 + 112) = 220 meter. Time = 6 seconds. Relative speed = 220/6 = 110/3 m/s. = (110 × 3600)/(3 × 1000) km/hr = 132 km/hr. Now, 50 + Speed of second train = 132 km/hr. ∴ Speed of second train = (132 - 50) km/hr. = 82 km/hr.

Bank Preparation Bank Math +১ more A train takes 50 sec to cross a boy travelling at 6 km/h in the opposite direction to it. Another train which is half as long as and 25% faster take 30 sec to cross the stationary pole. Find the approximate length of the second train. ক 100 m 1 125 m 2 190 m 3 148 m সঠিক উত্তর 1 (125 m) ব্যাখ্যা: Solution:Let m be the length of the first train. Let r be the speed of the first train in meters per second. then m=50(r+5/3m/s). Let n be the length of the second train. Since the second train is half as long as the first train we know that n=1/2m. Let 1.25r be the speed of the second train. The length of the second train is n = 30 ×1.25r Since n=1/2m we can substitute to make 1/2m=30 × 1.25r. Or m = 2 × 30 × 1.25r = 75r. m =75r. We can now combine the 2 equations: 50(r+5/3) = 75r 50r+250/3=75r 150r+250=225r 75r=250 r =10/3. m =75r = 75 × 10/3 = 250 meters. The second train is 125 meters long.
