Question

A regulation baseball field measures 90 feet between each base. What is the distance around the bases in yards

Answer 1

The distance between each base is 30 yards since 90*(1/3) = 90/3 = 30
In other words, 90 feet is equivalent to 30 yards (3 ft per 1 yard)

The total distance around the bases is 30*4 = 120 yards. This is the perimeter.
