The ratio of the distances a pitching wedge and an 8-iron will drive a golf ball is 4 to 5. If a golfer averages 140 yards with a pitching wedge, how far should she average with an 8-iron?

4/5 = 140/x

Cross multiply and solve for x.

4x = 700

x = 175

Thank you Ms. Sue.

You're welcome, Sam.

To find how far the golfer should average with an 8-iron, we can use the given ratio of 4 to 5. Let's call the distance with an 8-iron "x".

According to the ratio, we can set up the following proportion:

(140 yards)/(distance with a pitching wedge) = 4/5

To solve for "x", we can cross-multiply:

(140 yards) * (5) = (distance with a pitching wedge) * (4)

700 = (distance with a pitching wedge) * 4

Now, we can isolate the distance with a pitching wedge by dividing both sides by 4:

(distance with a pitching wedge) = 700 / 4

(distance with a pitching wedge) = 175 yards

Since the golfer averages 140 yards with a pitching wedge, we know that:

(distance with a pitching wedge) = 140 yards

Now, we can substitute this value into the equation:

175 yards = 140 yards * (5/4)

To find "x" (the distance with an 8-iron), we can divide both sides by (5/4):

(x) = 175 yards / (5/4)

Simplifying the expression on the right-hand side:

(x) = 175 yards * (4/5)

(x) = 140 yards

Therefore, the golfer should average 140 yards with an 8-iron.
