If a train is going at the rate of 40 kmph, it is late by 11 min. If it is going at the rate of 50 kmph, it is late by 5 mins to reach at a destination. Find actual time to complete the journey 

Answer & Explanation
Answer : Option
C


Explanation : 

$x$ = Actual time in minutes.
S $\times$ T = S $\times$ T
40 $\times$ $x + 11 \over 60$ = 50 $\times$ $x + 5 \over 60$
$x$ = 19 minutes
