SOFTBALL  Chloe pitches at a top speed 3 feet per second faster than Becky. If Chloe’s top speed is x feet per second, which expression represents how much longer it takes for ball to travel the 43 feet to the plate when Becky pitches?

Let's break down the problem step by step.

1. Identify the given information:

   • Chloe's top speed is $x$ feet per second.
   • Chloe pitches 3 feet per second faster than Becky.

2. Determine Becky's top speed:

   • Since Chloe pitches 3 feet per second faster than Becky, Becky's top speed is $x - 3$ feet per second.

3. Calculate the time it takes for Chloe's pitch to travel 43 feet:

   • Time is calculated by dividing the distance by the speed.
   • For Chloe: $\text{Time}_{\text{Chloe}} = \frac{43 \text{ feet}}{x \text{ feet per second}}$.

4. Calculate the time it takes for Becky's pitch to travel 43 feet:

   • For Becky: $\text{Time}_{\text{Becky}} = \frac{43 \text{ feet}}{(x - 3) \text{ feet per second}}$.

5. Determine the difference in time:

   • The difference in time is $\text{Time}_{\text{Becky}} - \text{Time}_{\text{Chloe}}$.
   • Substitute the expressions for time: $\text{Difference in time} = \frac{43}{x - 3} - \frac{43}{x}$

So, the expression that represents how much longer it takes for the ball to travel the 43 feet to the plate when Becky pitches is: $\frac{43}{x - 3} - \frac{43}{x}$
