Answer:

B. 30 KMS

Step-by-step explanation:

total distance travelled by pass. train = speed * time

= 78km/h * 5h = 390 kms

goods train distance = 390 kms. as the train overtakes, same distance by both trains

time taken by goods trtain (5h+8h) 13 hrs

speed = distance / time

=390 / 13 = 30

speed of goods train is 30 km/h
