Robots Moving on a Highway
Problem Statement:
The Linkbot moves 24 units. The Mindstorms moves Â¾ of that distance. How far does the Mindstorms move? Update the green block with the correct distance.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
#include <mindstorms.h>
double answer;
CLinkbotI robot1;
double radius1 = 1.75;
CMindstorms robot2;
double radius2 = 1.1;

robot1.driveDistanceNB(24, radius1);
robot2.driveDistance(24 * (double(3)/4), radius2);
robot1.moveWait();
printf("How far does the Mindstorms drive?"+"\n");
scanf("%lf", &answer);
