I need help with this peoblem:

A rope that is 30 feet long is tied to a weight and strung through a pulley that is 8 feet above the weight and is tied to the bumber of a car that is 2 feet from the ground. The car moves away from the weight at a rate of 5 feet/sec. How fast is the weight rising when it is 4 feet from the ground?

Forgive me if this makes no sense, but this is exactly how my professor worded the question and he thinks is makes perfect sense.
