Along the left side of a street that measures 30 m in length, maple trees are
planted at intervals of 5 m from the starting point. Along the right side of the same
street, ginkgo trees are planted at intervals of 6 m. What is the distance between
the starting point and the trees when the maple and ginkgo trees are at the same
distance for the first time?
Step 1. Find the distance between each maple tree and the starting point.
Step 2. Find the distance between each ginkgo tree and the starting point.
Step 3. Find the distance between the trees and the starting point when the
maple and ginkgo trees are at the same distance for the first time.
