Hare and the Tortoise

Haretown and Tortoiseville are 30 miles apart. A hare travels at 9 miles per hour from Haretown to Tortoiseville, while a tortoise travels at 1 miles per hour from Tortoiseville to Haretown.

If both set out at the same time, how many miles will the hare have to travel before meeting the tortoise en route?
