Kevin can clean a large aquarium tank in about 8 hours. When Kevin and Lara work together, they can clean the tank in 4 hours. Enter and solve a rational equation to determine how long, to the nearest tenth
of an hour, it would take Lara to clean the tank if she works by herself? Complete the explanation as to
whether the answer is reasonable.
It would take Lara about hours to clean the tank by herself. The answer is reasonable because It
is positive v and, when substituted back into the equation, the equation is true.
