Thank you so much I was stuck on it for a while.
To find an equivalent rate, we need to compare the number of tasks completed to the amount of time it takes. In this case, Khalid completed 40 tasks in 90 minutes.
Now, let's find out how many tasks Khalid completed in 1 minute. We can do this by dividing the number of tasks (40) by the amount of time (90).
40 tasks ÷ 90 minutes = 0.4444 tasks per minute
Now that we know Khalid completed 0.4444 tasks per minute, we can compare this to the answer choices provided:
A) 10 tasks in 0.9 minutes: This would be 10 tasks ÷ 0.9 minutes = 11.11 tasks per minute, which is higher than the rate calculated.
B) 10 tasks in 2.25 minutes: This would be 10 tasks ÷ 2.25 minutes = 4.44 tasks per minute, which is lower than the rate calculated.
C) 10 tasks in 9 minutes: This would be 10 tasks ÷ 9 minutes = 1.11 tasks per minute, which is significantly lower than the rate calculated.
D) 10 tasks in 22.5 minutes: This would be 10 tasks ÷ 22.5 minutes = 0.44 tasks per minute, which is the closest rate to the calculated one.
So, the answer is option D) 10 tasks in 22.5 minutes.
