sorry don't remember the "trick" to doing these kind of rate problems
let tota wrk done be W
ok so cody completes in 8hrs
so the work that he does in 1hr is W/8
and Kaitlyn completes wrk in 6hrs
so wrk done in 1hr= W/6
so when the both wrk together
wrk done in 1hr =W/6 + W/8
1hr ------>7W/24 of wrk
24/7hrs------->W wrk :)
