Let the correct time to complete the journey be x min.
Distance covered in (x + 11)
min.= Distance covered in (x + 5) min at 50 km/hr
∴ (x+11)60 * 40
(x+5)60 * 50
=x = 19 min.

Let us consider the time of journey be T hrs
then,as distance is same, then
A/Q,
⇒40( T +11/60) =50 (T- 5/60)
⇒T= 23/30 hr
distance= speed ×time
              = 40×23/30
              =92/3 km
              =30.66 km
