Answer:
A sloth can move 600 units in 90 minutes.
Explanation:
The problem says that if you divide 250 in
you obtain how far a sloth move in one hour, then:

A sloth moves 400 units in one hour (60 minutes).
We can use a rule of three,
400 units ⇒ 60 minutes
x ⇒ 90 minutes

A sloth can move 600 units in 90 minutes.
