**Jai**, Wednesday, October 26, 2011 at 1:49amrecall that rate is just distance travelled over time, or

v = d/t

let x = time required for them to meet

thus since they are paddling toward each other, we add their rates and multiply it by the time required and equate this distance to 33:

(4 + 7)x = 33

11x = 33

x = 3 hours

hope this helps~ :)
