Homework Help: AP calc for situational problem involving rate and time.

  1. Jan 22, 2012 #1
    1. The problem statement, all variables and given/known data

    Water is pumped out of a lake at the rate R(t) = 12*SQUAREROOT(t / t+1) cubic meters per minute, where t is measured in minutes. How much water is pumped from time t = 0 to t = 5 ?

    2. Relevant equations

    3. The attempt at a solution
    I cannot figure out if the integration of times 0 and 5 are all that is required or if I will have to also convert cubic meters before completing problem.

    the integration would leave you with cubic meters anyway, you wouldn't need to do any converting
    the question also doesn't ask for a specific unit so I'd guess you would be alright using whatever units you wanted
