Can you help with my Precalc?

the question says “a rectangular animal pen is built. One side of it is the wall of a barn. It is 1680 ft sq. If Tom can put up the fence in 12 hours, how fast will bob have to work so that the fence is put up in 8 hours? How long will it take bob to do it on his own?”
im so confused. Please help me :(
