Yu Wang from Bern in Switzerland sent this:

The tortoise takes 2 hrs 30 mins to complete the race. Divide that by 10 to give you 15 mins (this is how long the hare takes), substract 15 mins from 2 hrs 30mins and then add the 30 seconds because the hare finishes 30 seconds after the tortoise.

T (hare ) = 2 hrs 30 mins 30 secs -15 mins So, the hare sleeps for 2 hours 15 minutes and 30 seconds.
