Question

if a train runs at 40 km per hour it reaches is destination late by 11 minutes but if it runs at 50 km per hour it is late by 5 minutes find the distance to be covered by the train​

Answer 1

Step-by-step explanation:

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.
