Add 240 mg to a liter of water. You may end up with a volume > 1 liter. In that case, add more KHP until M(KHP)/240 = V'. Then discard V' - 1 liter, leaving yourself with 1 liter containing 240 mg of KHP.

Well, 4 seconds after crossing, the train has traveled 240 m. Draw your figure, lets are 60, 240, and the hypotenuse is L=sqrt (60^2+240^2) But in general, l^2=x^2+60^2 2L*dL/dt=2x dx/dt you are solveing for dL/dt, you know x, dx/dt, and L.

Is this f'(x) or partial derivative?
If VC(y)=((y/240)^2)(w) then VC is not dependent on w, so if you differentiate as a product, the term containing dw/dy drops out (because dw/dy=0), giving you the correct answer. If w is a function of y, namely w=w(y), then the term dw/dy should be kept: d(VC)/dy = 2yw/240^2...
