Will give EXTRA points. If the answer is 17.5 please explain what happened to 180 & 160!!! This is the question that was answered “ URGENT! Justin's sand castle is 180 cm tall but the wind is blowing away sand at a rate of 8 cm per minute. Taylor's sand castle is 160 cm tall and she is adding sand to it at a rate of 6 cm per minute. After how many minutes will their sand castles be at an equal height?”
