The battalion covered 20 kilometers in 4 hours through the marsh. When the terrain changed, their speed was tripled. How many kilometers could the cover in 6 hours after the terrain changed?

Brainliest pls?

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.

yes. we do proportions in probabilities.
