Question

the distance between two station is 340 km two trains start simultaneously from the stations on parallel tracks to cross each other the speed of one of them is greater than that of other by 5 kilometre per hour if the distance between the two trains after 2 hours of their start is 30 find the speed of each train ​

Answer 1

Step-by-step explanation:

let the speed be x km/h

distance =340 km

time for 1st train= distance /speed

340/× sec

now,2nd train ,

same speed initially

distance =340 km( speed increase)

time for 2nd train =340/x+5 km/h

total time (t1-t2)= 2 hours

340/×-340/×+5=2

so next...step...is simple calculate it
