Verified Answer
A train travels for 30mins with a velocity of 36km/h and then for 40 m...
Ans.

Method to Solve :

First we will calculate the distance of first 30 min then for next 40 min and then find the average.
Velocity= distance/ time.
Distance in first 30 minutes is 36*1/2= 18 km
Distance in next 40 minutes is 54*2/3= 36 km

Now we will find the final distance traveled which comes out to be 18+36=54 km
Now total time taken is 7/6 hr
Average velocity is 54/(7/6) = 46.285 km/hr.

Hence we first calculate the total distance traveled then total time taken. Then we get out velocity.
