Problem Statement:

You want to use robot to drive around town, but your robot has only 1 drive program: driveDistance(144 , radius). You discover that you can scale the drive() program - multiply or divide it by any number - and that will drive you to any location your want. The codes are pre-loaded. Input the correct scaling values into the two "drive with x ()" commands to drive the robot to place A (y = 48) first and then to place B (y = 144).
