Question

A strawberry jello salad recipe requires 10 minutes of prep and 4 hours to chill in the refrigerator. What time should you begin preparing it if it is to be ready for 5:00 pm?

Answer 1

You would need to start at 12:50 pm.

To solve this problem, you want to work backwards and find 4 hours and 10 minutes before 5:00 pm.

Well, to find 4 hours before 5:00 pm, subtract 4 from 5. you are left with 1:00 pm. Now, you need to find 10 minutes before that. To do this, you want 10 minutes before the turn of 1:00, so since the hour before 1 is 12, Your time would be 12:50, 10 minutes before 1:00.

I hope this helps and have a great rest of your day!
