Ravi walks $$6$$km in an hour while Roshan walks $$4$$km in an hour. What is the ratio of the distance covered by Ravi to the distance covered by Roshan?
distance covered by Ravi in $$1$$ hr = $$6$$ km
distance covered by Roshan in $$1$$ hr = $$4$$ km
ratio of the distance covered by Ravi in $$1$$ hr to distance covered by Roshan in $$1$$ hr = $$6$$ km : $$4$$ km
=$$6$$ : $$4$$
= $$3$$ : $$2$$
