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
