Two Robot Track Race
Problem Statement:
The red robot moves at 4 in/sec. If the red and green robots race for 36 inches, how fast should the green robot move if it finishes the race 3 seconds after the other robot? Add a setSpeed block for the green robot.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot1;
double radius1 = 1.75;
CLinkbotI robot2;
double radius2 = 1.75;

robot1.setSpeed(4, radius1);
robot2.setSpeed(3, radius2);
robot1.driveDistanceNB(36, radius1);
robot2.driveDistance(36, radius2);
robot1.moveWait();
