TIME TAKEN FORMULA FOR TWO TRAINS PASSING EACH OTHER

$\bold{\underline{\underline{ANSWER}}}$

Here we will learn about the concept of two trains passes in the opposite direction.

Here we will learn about the concept of two trains passes in the opposite direction.When two train passes a moving object (having some length) in the opposite direction

Here we will learn about the concept of two trains passes in the opposite direction.When two train passes a moving object (having some length) in the opposite directionLet length of faster train be l meters and length of slower train be m meters

Here we will learn about the concept of two trains passes in the opposite direction.When two train passes a moving object (having some length) in the opposite directionLet length of faster train be l meters and length of slower train be m metersLet the speed of faster train be x km/hr

Here we will learn about the concept of two trains passes in the opposite direction.When two train passes a moving object (having some length) in the opposite directionLet length of faster train be l meters and length of slower train be m metersLet the speed of faster train be x km/hrRelative speed = (x + y) km/hr.

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr                               = 72 km/hr

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr                               = 72 km/hr                               = 72 × 5/18 m/sec

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr                               = 72 km/hr                               = 72 × 5/18 m/sec                               = 20 m/sec

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr                               = 72 km/hr                               = 72 × 5/18 m/sec                               = 20 m/secTime taken by the two trains to cross each other = sum of length of trains/relative speed of trains

Two trains of length 150 m and 170 m respectively are running at the speed of 40 km/hr and 32 km/hr on parallel tracks in opposite directions. In what time will they cross each other?Solution:            Relative speed of train = (40 + 32) km/hr                               = 72 km/hr                               = 72 × 5/18 m/sec                               = 20 m/secTime taken by the two trains to cross each other = sum of length of trains/relative speed of trains                                                                   =(150 + 170)/20 sec

(150 + 170)/20 sec                                                                   =320/20 sec

(150 + 170)/20 sec                                                                   =320/20 sec                                                                   =16 sec

(150 + 170)/20 sec                                                                   =320/20 sec                                                                   =16 secTherefore, the two trains crossed each other in 16 seconds.
