Two swimmers start at opposite ends of a 90-feet rectangular pool. One swims 30 feet per minute and the other swims 20 feet per minute. If the swimmers keep swimming laps for a long time, how often and when will the swimmers meet each other (or be directly next to each other in their own lanes)? At what locations in the pool will this happen? Solve this in as many ways as you can.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
