[Question]It takes Omar 12 minutes to raise his kite 240 feet into the air. Jasper can raise his kite at three times the rate of speed as Omar can raise his kite. If Jasper raises his kite to a height of 600 feet, how many minutes will it take?
[Answer]Jasper raises his kite at a rate of 240 feet in 12 minutes, or 240 / 12 = 20 feet per minute. Jasper raises his kite at three times the speed Omar does, or 3 * 20 = 60 feet per minute. To raise his kite 600 feet, it will take Jasper 600 / 60 = 10 minutes. The answer is 10.

[Question]Debelyn, Christel, and Andrena collect dolls. Debelyn had 20 dolls before she gave Andrena 2 dolls. Christel had 24 dolls before giving Andrena 5 dolls. After all the gifts, Andrena now has 2 more dolls than Christel, how many more dolls does andrena have now than Debelyn?
[Answer]Debelyn had 20 - 2 = 18 dolls left after giving out 2 dolls to Christel. Christel had 24 + 2 = 26 dolls after receiving 2 dolls from Debelyn. Christel had 24 - 5 = 19 dolls after giving Andrena 5 dolls. So, Andrena has 19 + 2 = 21 dolls now. Therefore, Andrena has 21 - 18 = 3 more dolls than Debelyn. The answer is 3.

[Question]Joel collected a bin of old toys to donate. By asking his friends, he was able to collect 18 stuffed animals, 42 action figures, 2 board games, and 13 puzzles. His sister gave him some of her old toys from her closet, and then Joel added twice as many toys from his own closet as his sister did from hers. In all, Joel was able to donate 108 toys. How many of the donated toys were Joel’s?
[Answer]Let T be the number of toys Joel’s sister donated. Joel donated twice as many toys, so he donated 2T toys. Joel’s friends donated 18 + 42 + 2 + 13 = 75 toys. In all, Joel collected T + 2T + 75 = 3T + 75 = 108 toys. Joel and his sister donated 3T = 108 - 75 = 33 toys together. Therefore, T = 33 / 3 = 11 toys were his sister’s. Thus, 2T = 2 * 11 = 22 toys were Joel’s. The answer is 22.
