Penelope has been practicing driving a golf ball. The lengths of her first 3 drives are shown below: • Drive 1: 180 yards • Drive 2: 170 yards • Drive 3: 195 yards • Drive 4: ? How far does she need to drive the ball so that her average drive is 182 yards? yards

Answer 1

The answer is "183 yards"

Explanation:

`Drive \ 1= 180 \ yards \\\\Drive \ 2= 170 \ yards\\\\ Drive\ 3= 195 \ yards \\\\Drive \ 4= x \ \ yards \\\\`

Using formula:

`\to \text{average of number}=(sum \ of \ number)/(total\ number)\\\\\to 182 =(180+170+195+x)/(4)\\\\\to 4 * 182 =545+x\\\\\to x= 728-545\\\\\to x=183`
