Question

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?

Answer 1

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

`$\frac{\text { Distance using } 7 \text { iron }}{\text { Distance using } 5 \text { iron }}=(5)/(6)$`

The golfer averages 181 yards with a 7-iron

Let "x" be the average with 5 - iron

Therefore,

`(181)/(x)=(5)/(6)`

Cross mulitply to get value of "x"

`6 * 181=5 * x\\\\5x = 1086\\\\x = (1086)/(5)\\\\x = 217.2`

Thus he should average 217.2 yards with 5 - iron
