The ratio of the distance a 7-iron and a 5-iron will drive a golf ball 5to6. if a golfer averages 181 yards with a 7-iron, how far should he average with a 5-iron?

He should average 217.2 yards with 5 - iron

Solution:

Given that,

Ratio of the distance a 7-iron and a 5-iron will drive a golf ball 5 to 6

The golfer averages 181 yards with a 7-iron

Let "x" be the average with 5 - iron

Therefore,

Cross mulitply to get value of "x"

Thus he should average 217.2 yards with 5 - iron

5+2x=a
