x = amy's cycling speed.
y = peter's cycling speed.
peter cycles twice as fast as amy.
y = 2x
solve for x to get x = 1/2 * y
amy cycles half as far as peter.
we do not know the cycling speed of either peter or amy.
we only know that peters cycles twice as fast as amy and that amy cycles half as fast as peter.
if we knew peters's cycling speed, we could find amy's.
if we knew amy's cycling speed, we could find peter's.
we only know that, whatever amy's speed is, peter's is twice as fast.
we only know that, whatever peter's speed is, amy's is half as fast.
