This is all you need for conversions:

1cm3 = 1 ml ... thus 40 cm3 = 40 ml

So to make it faster I would do it like this

40 ml/sec * 60 sec/1min * 1L/1000ml = 2.4 L/min

If, like me, you dislike memorizing formulas, but are okay doing the actual math, I always just look at the units. It wanted L/min, and I had to get it using cm^2 and cm/sec...

Well, I know cm^3 gives volume (L) after bashing out a few conversions, so multiply it is!

Then I know to turn seconds into minutes, so multiply by 60.

Now, at this point, I knew my decimals were off, but still, 4x6 = 24, so it's some version of that. Had they included 24 or .24 as answers, I'd have actually had to pay attention to my conversions.

Anyways, I hope that helps!
