Hello!
First, you'll need to convert 30% into a decimal. You can do this by moving 30's decimal place twice to the left to get 0.30. Now you'll need to multiply 0.30 with 160km to get 30% of 160. Once you've done that you should have 48. Now to increase 160km by 30%, you'll need to add 48 to 160 to increase it by 30%. Once you've done that, you should have an answer of 208km.
I hope this helps!
