Question 981262: On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles per hour from his rate on his return trip. Alfonso found that in the same amount of time he could cycle 66 miles with the wind, he could go only 42 miles against the wind.What is his normal bicycling speed with no wind?

Alfonso found that in the same amount of time he could cycle 66 miles with the wind, he could go only 42 miles against the wind.What is his normal bicycling speed with no wind?
===================
The windspeed is not added to or subtracted from bicycle speed. It's not a linear relationship.
----
If you pedal North at 10 mi/hr, and the wind is from the left side at 10 mi/hr, you don't go to the north-east.
This is another instance of someone writing a math problem, but doesn't know what he/she is talking about.
=====================
You'll have to supply the relationship to use.
