Question

A robot can complete 7 tasks in an hour. Each task takes the same amount of time.

a. How long does it take the robot to complete one task?

Option 1: 7 hours
Option 2: 0.14 hours
Option 3: 1 hour
Option 4: 14 hours

Answer 1

To calculate the time it takes for a robot to complete one task, divide the total time (60 minutes) by the number of tasks (7), resulting in approximately 8.57 minutes per task, or 0.14 hours. Hence, the correct answer is Option 2: 0.14 hours.

Step-by-step explanation:

The question asks how long it takes for a robot to complete one task if it can complete 7 tasks in one hour. To find the time taken for one task, we need to divide the total time available (1 hour) by the number of tasks (7). One hour can also be written as 60 minutes, so we perform the following calculation:

• Time for one task = Total time / Number of tasks
• Time for one task = 60 minutes / 7 tasks
• Time for one task ≈ 8.57 minutes

Converting minutes to hours, we find that:

• 8.57 minutes ÷ 60 minutes per hour ≈ 0.1428 hours

Therefore, the correct answer is Option 2: 0.14 hours.

Given the provided information, we can state that:

• The time taken for one task is less than seven hours.
• The sum of all these times is how long it would take to get all of these tasks done.
• The probability that the robot takes less than one hour to complete one task is 1 (a certainty).
