Question

Alex was pestering his little sister the other day. Unfortunately, she had in her possession a couple of water balloons. Alex runs away at 3 m/s. First, he runs for 2 seconds directly away from her (0 degrees). Then he remembers from all the good movies the he needed to zig-zag to decrease the chance of being hit. So he zigs at 25 degrees for 3 seconds. Then he zags for 5 seconds at -45 degrees. If his sister has excellent aim, how far and in what direction would she have to throw the water balloon to hit Alex 10 seconds after he runs away?
