Part 1. Fleas can jump 140times their own height. They jump so they land a max distance of 20.80cm away. What is their take off speed?

I got this part right already, got 1.43m/s what I really need help with is part 2...

Part 2. What is the flea's height?

2. Relevant equations

I think y=V0y*t-(1/2)gt^2 might be important but I really don't know

3. The attempt at a solution

I'm clueless. I think I have to find out how high the flea jumps and then divide by 140 but I am stumped. Any help is very appreciated!!
