Find the Required Speed of a Robot
Problem Statement:
The red robot moves around one block, tracing a square of 9" x 9". The green robot moves around four blocks, tracing a square of 18" x 18". Change the speed of the green robot so they take the same amount of time to move the required distance and the red robot does not need to wait for the green one.
