Dogs and Rabbits

“A dog chasing a rabbit, which has a start of 150 feet, jumps 9 feet every time the rabbit jumps 7.  In how many leaps does the dog overtake the rabbit?”

- from “Problems for the Quickening of the Mind,” by Alcuin (AD 735-804)

Nice little riddle to tell right away if someone has mathematical aptitude.
