hello. hope this helps you. if it does kindly mark me as brainliest :D

Step-by-step explanation:

taking operations on passenger train

we know that: speed = distance / time

substituting the values

80= distance/ 6

distance = 80*6 = 480 km

now substituting values of distance and time for good train:

speed= distance / time

= 480/4

= 120 km/h
