if a train runs at 40 kmph, it reach its destination late by 11 minutes but if it runs at 50 kmph it is late by 5 minutes only. the correct time for a train to complete its journey is? let the correct time to complete the journey be x min distance covered in ( x + 11 ) min. at 40 kmph distance covered in ( x + 5 ) min. at 50 kmph ( x + 11 ) / 60 * 40 = ( x + 5 ) / 60 * 50 x = 19 min Choose the correct choice from the following:  A) 19 min  B) 19 hrs  C) 52 min  D) 126 min  E) 52 min

if a train runs at 40 kmph, it reach its destination late by 11 minutes but if it runs at 50 kmph it is late by 5 minutes only. the correct time for a train to complete its journey is? let the correct time to complete the journey be x min distance covered in ( x + 11 ) min. at 40 kmph distance covered in ( x + 5 ) min. at 50 kmph ( x + 11 ) / 60 * 40 = ( x + 5 ) / 60 * 50 x = 19 min
divide(subtract(multiply(multiply(60, 40), 11), multiply(multiply(60, 50), 5)), subtract(multiply(60, 50), multiply(60, 40)))
let the correct time to complete the journey be x min distance covered in ( x + 11 ) min . at 40 kmph distance covered in ( x + 5 ) min . at 50 kmph ( x + 11 ) / 60 * 40 = ( x + 5 ) / 60 * 50 x = 19 min answer ( a )
