Linear interpolation

The value of an avar controlling the yy-coordinate of a ball is 115115 in frame 33, and 240240 in frame 2828. The yy-coordinate of the ball between those frames is determined by linear interpolation.
What is the value of the ball's yy-coordinate in frame 1010?
  • Your answer should be
  • an integer, like 66
  • a simplified proper fraction, like 3/53/5
  • a simplified improper fraction, like 7/47/4
  • a mixed number, like 1 3/41\ 3/4
  • an exact decimal, like 0.750.75
  • a multiple of pi, like 12 pi12\ \text{pi} or 2/3 pi2/3\ \text{pi}
