Question

A train at 70 km/h it reaches its destination late by 12 min but if it runs at 80 km/h itvreaches 3 min earlier find the actual time to cover the journey

Answer 1

Step-by-step explanation:

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
