3 new classes are needed to be formed.

18 x 35 = 630

630 / 30 = 21

21 - 18 = 3

18 x 35 = 630

630 / 30 = 21

21 - 18 = 3

165 miles are actually between the two towns.

3 2/3 = 11/3

11/3 divided by 1/3

11/3 x 3/1 = 11in

11 x 15 = 165 miles

3 2/3 = 11/3

11/3 divided by 1/3

11/3 x 3/1 = 11in

11 x 15 = 165 miles
