Question

Lee is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assemble them in the pot. Then, the chili will need to simmer for 1 hour. What is the latest time Lee can start preparing the ingredients if the chili needs to be ready at 1:15 P.M.?

A) 11:05 AM
B) 10:05 AM
C) 10:45 AM
D) 11:15 AM

Answer 1

To have the chili ready by 1:15 PM, Lee should start preparing the ingredients and assembling them in the pot by 11:05 AM (1:15 PM - 2 hours and 10 minutes). Therefore, the latest time Lee can start preparing the ingredients is 11:05 AM (Option A).

Answer 2

The latest time Lee can start preparing the ingredients to ensure the chili is ready by 1:15 P.M. is 11:05 A.M. Subtract the preparation and simmering times from the target ready time to determine the latest start time. The correct answer is A) 11:05 AM.

Step-by-step explanation:

To find the latest time Lee can start preparing the ingredients for the chili, we need to work backward from the time the chili needs to be ready.

The chili needs to be ready by 1:15 P.M., and it requires 1 hour to simmer after the initial preparation. Before simmering, the preparation time is 1 hour and 10 minutes. We need to subtract these two periods of time from 1:15 P.M. to get the latest start time.

First, subtract the 1-hour simmering time from 1:15 P.M., which gives you 12:15 P.M. Next, subtract the 1 hour and 10 minutes of prep time from 12:15 P.M.

To do this, subtract 1 hour to get 11:15 A.M., and then subtract 10 more minutes to arrive at 11:05 A.M., which is the latest time Lee can start preparing the ingredients.
