Answer:
Ron to Bill = 67 yd
Bill to John = 30 yd
Total number of yards = 97 yd
Explanation:
See the figure below.
Use the Pythagorean theorem to find the distance from Ron to Bill.
a² + b² = c²
60² + 30² = c²
c² = 3600 + 900
c² = 4500
c = √4500
c = 67
Ron to Bill = 67 yd
Bill to John = 30 yd
Total number of yards = 97 yd
