It would be 20.4 km because if 1cm is 12km then you just have to multiply 1.7 x 12 = 20.4.
20 = 8 + v equals v = 12.
First, subtract 8 from both sides. Your problem should look like: 20 - 8 = v
Second, simplify 20 - 8 to get 12. Your problem should look like: 12 = v.
Third, switch sides to get v = 12, which is the correct answer.
If you are asking when you divide ten into a number, remember this, anything that ends with a 0, it is divisible by 10.
