Question

keavin completed 40% of his chores. he has been working for 20 minutes. how much longer will it take to finish his chores

Answer 1

It will take Keavin 30 minutes more to finish his chores, based on the calculation that 40% took 20 minutes to complete.

Step-by-step explanation:

To calculate the remaining time Keavin needs to finish his chores, we need to use the information that he has completed 40% of his chores in 20 minutes. To find the total time needed to complete all chores, we need to figure out how long it takes to do 100% of the chores. If 40% takes 20 minutes, we can find the time for 100% by dividing 20 minutes by 40% and then multiplying by 100%.

Let's do the calculation step by step:

1. Divide the time taken (20 minutes) by the percent completed (40%): 20 / 0.40 = 50 minutes. This means it takes 50 minutes to complete all chores.
2. To find out how much longer it will take him to finish, subtract the time already spent from the total time needed: 50 minutes - 20 minutes = 30 minutes.

Therefore, it will take Keavin 30 minutes more to finish his chores.
