Question 981961: On a particular day, the wind added 3 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 3 miles per hour from his rate on his return trip. Alfonso found that in the same amount of time he could cycle 48 miles with the wind, he could go only 30 miles against the wind.What is his normal bicycling speed with no wind?

Wind speed is 3 mph.
r, Alfonso's rate when no wind.
t, time for specific what he "found".
______________________speed__________time_________distance
withWind______________r+3_____________t____________48
againstWnd____________r-3_____________t____________30
Uniform Travel Rates Rule: RT=D,
T=D/R
The times for with and against wind are the same t.
Solve for r.
