The ratio of the distances between a driver and a 2- iron is 5 to 4. If a golfer averages 233 yards with a 2- iron, how far should she average with a driver?
If she averages 233 with a 2-iron, and a driver beats a 2-iron by a 5/4 ratio, the comparison is 5/4 = x/233 => x=233 * 5/4. She should average 291.25 yards.
