All the members of a construction crew work at the same pace. Four members of the crew, working together, are able to pour foundations in 32 hours.

If y is the number of hours it takes to pour foundations, and x is the number of construction workers, y=k/x, because it takes less time the more workers there are. So 32=k/4 and k=128 and y=128/x. The constant of variation is 128.
