Given the volume flow rate (volume/time) of a faucet and the volume of a bath tub, find the amount of time it takes to fill the tub 3/4 of the way.
Have z as the volume flow rate, and x as the volume of the tub.
You need more than one test case in your test suite.
Not to mention that the solution to the one test case is wrong. If q (volume flow rate) = v/t (volume/time), then t = v/q, not v*q.
What! No, the correct answer is 5*.75/5 == .75
Maybe the units are different? :-)
Fixed the test suite.
