Answer
If you stay healthy and able to walk 4 miles every day and don't add calories to offset your exercise burn, you could lose the 20 pounds in about 25 weeks. That is actually a very good plan, as you NEVER want to lose more than 1.5 pounds per week, which would get you there in about 14 weeks. The latter plan would take some (but not too much) daily cutting of calories. The slow weight loss makes it easier to keep the weight off, which should be your ultimate goal.

I say "if you stay healthy" because to suddenly start walking 4 miles per day might be too much, too soon. You need to allow time for your body to adapt to the exercise. Your muscles get stronger faster than than your tendons and ligaments. And this fact can lead to injuries if you are not careful.

A more careful plan would have you walking 1-2 miles per day for a few weeks before increasing it to 2-3 miles per day. 3-4 and 4-5 miles per day could be reached a few weeks after that.
