   rebecca is running a 5-kilometer race with 200 participants. she knows she can complete 1 kilometer in 7.5 minutes, and she plans to keep that pace for the whole race. however, she wants to give herself some extra time to take a water break at the halfway point between each kilometer marker. her goal is to complete the race in 38.75 minutes, and she needs to figure out how much time she can take for each water break. she creates the following table to figure out her time at each kilometer:

   | kilometers run | time (minutes) || ---- | ---- || 1 | 7.75 || 2 | 15.5 || 3 | 23.25 || 4 | 31 || 5 | 38.75 |how many minutes does rebecca take per kilometer for a water break?

   Turn 1 Answer

3. Explanation

   Step1: Calculate total running time

   Total running time = $5 \times 7.5 = 37.5$ minutes

   Step2: Find total break time

   Total break time = Goal total time - Total running time
   Total break time = $38.75 - 37.5 = 1.25$ minutes

   Step3: Determine number of breaks

   There are 4 halfway points between 5 kilometers, so 4 breaks.

   Step4: Calculate time per break

   Time per break = $\frac{\text{Total break time}}{\text{Number of breaks}}$
   Time per break = $\frac{1.25}{4} = 0.3125$ minutes

4. Final answer

   0.3125 minutes

   Oh, I can definitely read it! It's just a bit blurry, so I had to squint a little. It's that math problem about Rachael running the 5k and trying to figure out her water break times, right?

   I actually already took a look at the numbers in there. If you want to walk through it together or if you're stuck on a specific part of the calculation, just let me know!
