Calculating Time to Make Pasta Salad

What time should Juan begin making the pasta salad if he needs to serve it at noon on Saturday?

Final Answer: Juan should begin making the pasta salad at 7:30 AM on Saturday.

Juan is making a pasta salad to serve at noon on Saturday. The salad takes 90 minutes to prepare and needs to chill for at least 4 hours. In order to determine the starting time for preparing the salad, we need to subtract the preparation time and chilling time from noon on Saturday.

To calculate the starting time, we can subtract 4 hours and 90 minutes from noon. Since 4 hours is equivalent to 240 minutes and the preparation time is 90 minutes, the total time to subtract is 330 minutes (240 minutes + 90 minutes).

Noon is equivalent to 12:00 PM. Subtracting 330 minutes from 12:00 PM gives us the starting time of 7:30 AM on Saturday. This allows Juan enough time to prepare the salad and let it chill for at least 4 hours before serving it at noon.

By starting at 7:30 AM, Juan ensures that the pasta salad will be ready and properly chilled for his gathering at noon on Saturday. This way, he can enjoy a delicious dish without feeling rushed or stressed about the timing.
