TODAY’S Q: 

A kayaker paddles up the Liffey and can paddle at 9 km/h in still water. However, the Liffey is flowing towards the sea at 5 km/h. The very moment he passes under Butt Bridge, 2.5 km upstream, a kayaker passes Heuston Bridge heading downstream.

The canoeists meet after 10 minutes.

Which kayaker is the stronger paddler?

All answers will be published on TheJournal.ie on Sunday morning.
