Answer:
They could cover 90 kilometres in 6 hours, after the terrain changed.
Step-by-step explanation:
Their speed, when they were traversing through the marsh, is:
speed = distance/time
s = 20 km / 4hr
s = 5 kmph
If their speed tripled, then it will be: 5*3 = 15 kmph
distance = speed * time
d = 15 km/h * 6h
d = 90 km
They could cover 90 kilometres in 6 hours, after the terrain changed.
