You need more than one test case in your test suite.

Guillaume on 4 Feb 2015

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.

3.75 ?

Guillaume on 5 Feb 2015

What! No, the correct answer is 5*.75/5 == .75

Maybe the units are different? :-)

Fixed the test suite.
