There are $$9$$ benches in the park, which have the same length. They are placed on one side of the road every $$7$$ meters from end to end. Given that the length of the road is $$74$$ meters, how long is the bench?

The $$9-1=8$$ intervals are $$7\times8=56$$ meters in total.  So, the sum of length of all the benches is $$74-56=18$$ meters and each of them is $$18\div9=2$$ meters.
