Two men lived at the top of a cliff of height 200 meters. The base of the cliff was 400 meters from a neighbouring village. One man climbed straight down the cliff and walked to the village. The other, being a wizard, flew straight up 'x' meters and then in a straight line to the village. If both men travelled the same distance, find 'x'

the man walked straight down the cliff and across, thats 200m +400m which is 600m
if both men walked the same distance than x = 600m
if both men walked the same distance than x = 600m
