1. the table shows ms. kayla’s ged® students’ results from a keyboarding ... difference in words per minute (wpm) between the fastest- and the slowest-...

name	words typed	minutes
derrick	67	2
toneshia	84	2
connie	70	2
frank	59	2

Explanation:

To find the difference in words per minute (wpm) between the fastest - and the slowest - typing students, we first need to calculate the wpm for each student using the formula \( \text{wpm}=\frac{\text{Words Typed}}{\text{Minutes}} \).

Step 1: Calculate wpm for each student

• For Percy:

We know that the number of words typed is 90 and the number of minutes is 2. Using the formula \( \text{wpm}=\frac{\text{Words Typed}}{\text{Minutes}} \), we substitute the values: \( \text{wpm}_{\text{Percy}}=\frac{90}{2} = 45 \) wpm.

• For Derrick:

The number of words typed is 67 and minutes is 2. So, \( \text{wpm}_{\text{Derrick}}=\frac{67}{2}=33.5 \) wpm.

• For Toneshia:

The number of words typed is 84 and minutes is 2. Then, \( \text{wpm}_{\text{Toneshia}}=\frac{84}{2} = 42 \) wpm.

• For Connie:

The number of words typed is 70 and minutes is 2. Thus, \( \text{wpm}_{\text{Connie}}=\frac{70}{2}=35 \) wpm.

• For Frank:

The number of words typed is 59 and minutes is 2. So, \( \text{wpm}_{\text{Frank}}=\frac{59}{2} = 29.5 \) wpm.

Step 2: Identify the fastest and slowest wpm

From the calculated wpm values:

• The fastest wpm is 45 (Percy).
• The slowest wpm is 29.5 (Frank).

Step 3: Calculate the difference

To find the difference between the fastest and slowest wpm, we subtract the slowest from the fastest: \( 45 - 29.5=15.5 \)

Answer:

The difference in words per minute between the fastest - and the slowest - typing students is \( \boldsymbol{15.5} \) wpm.
