Question 963148
The wind is blowing an average of 10 mph. riding with the wind the bicyclist can cycle 75 miles in the same amount of time it takes the cyclist 15 miles against this same wind. what is the bicyclist's average rate in calm air?
======================
The effect of wind on a bicyclist is not clearly defined.
The windspeed is not added or subtracted as it is on an airplane.
-----------------
A wind at 90 degrees from the heading of the bicycle does not sent the bicycle on a resultant course.
Anyone who has ridden a bicycle knows this.

People who don't know what they're doing should not write math textbooks.
They should stick to politics.
