[Question]: It takes Polly 20 minutes to cook breakfast every day. She spends 5 minutes cooking lunch. She spends 10 minutes cooking dinner 4 days this week. The rest of the days she spends 30 minutes cooking dinner. How many minutes does Polly spend cooking this week?
[Answer]: Polly spends 20 * 7 = 140 minutes cooking breakfast. She spends 5 * 7 = 35 minutes cooking lunch. She spends (10 * 4) + (30 * 3) = 130 minutes cooking dinner. Therefore, she spends 140 + 35 + 130 = 305 minutes cooking this week.
So the answer is 305.

[Question]: Hadassah took six hours to paint 12 paintings. What would be the total time she's taken to finish all the paintings if she paints 20 more paintings?
[Answer]: If it took Hadassah six hours to paint 12 paintings, then she paints 12 / 6 = 2 paintings in an hour. If two paintings take an hour to complete, 20 paintings will take 20 / 2 = 10 hours. The total time she took to finish all the paintings is 10 + 6 = 16 hours.
So the answer is 16.

[Question]: Belinda can throw a ball at a speed of 20 feet/second. If the ball flies for 8 seconds before hitting the ground, and Belinda's border collie can run 5 feet/second, how many seconds will it take the border collie to catch up to the ball?
[Answer]:
First find the total distance the ball flies: 20 feet / second * 8 seconds = 160 feet. Then divide that distance by the dog's speed to find how long it takes the dog to catch up to the ball: 160 feet / 5 feet / second = 32 seconds.
So the answer is 32.
