# A gentleman and his yacht

**Logic**Level 3

A gentleman with a top hat is taking a ride in his fabulous yacht in a long river at. (The yacht moves at a constant velocity \(v\) which is affected by the direction/speed of the current) He sailed his yacht against the current of the river for 1 mile, but at that point his hat blew off and landed in the river.

He didn't notice this for 30 minutes, until it began to drizzle and he realized his hat must have blown off. Upon realizing this he turned around, like a true gentleman, and embarked on a quest to retrieve his hat.

Amazingly, he reached the dock he started at at the same time his hat did! What was the rate of the current in miles per hour? (And yes, you have enough information)
