Okay, this may sound silly... but it's driving me crazy! Some time ago, my friend showed me an extra credit problem for her class and ever since I haven't been able to figure it out. Now classes are over and we've all moved home, but it's still bugging me to no end. So, if you can help... please do!
A boat starts traveling down a river on a boat at point A and at point B a hat falls out of the boat (and floats), but the driver doesn't realize that the hat fell out until he reaches point C. The man turns around the boat and meets up with the hat at point D.
The distance between point A and B is 1 mile.
The time it takes to travel from point B to C is 20 minutes.
It takes the same amount of time for the boat to travel to point C to D as it takes the hat to travel from point B to point D.
The boat is traveling at a constant speed.
What is the current of the water?
And here's a little diagram of the picture her teacher drew them.
C (current is headed downward)
B
A D
Help!
