I need help on how to work this problem out. I need step by step please.

This is the word problem:
On Monday, I rode 9 miles. On Sunday, I rode 4 fewer days than on Monday. On Tuesday I rode 2 times farther than Sunday. How far did I ride on those 3 days?

On Monday, I rode 9 miles. + 9

On Sunday, I rode 4 fewer miles than on Monday + 5
On Tuesday I rode 2 times farther than Sunday + 10

Add those numbers together. What do you get?
