Question: It takes John 13 seconds to run 100 meters. He only goes 4 meters in the first second. He then maintains the same speed for the rest of the race. James is 2 m/s faster at the top speed and he can run the first 10 meters in 2 seconds. How long does it take James to run 100 meters?
Answer: John runs 100 - 4 = 96 meters once he reaches his max speed. He runs it in 13 - 1 = 12 seconds. So he runs at a speed of 96 / 12 = 8 m / s. So that means James's top speed is 8 + 2 = 10 m / s. He has to run 100 - 10 = 90 meters at his top speed. So he runs that at 90 / 10 = 9 seconds. So he takes 9 + 2 = 11 seconds to run 100 meters. The answer is 11.
[Question]If Billy rode his bike 17 times, John rode his bike twice as many times, and their mother rode her bike 10 times more than John, how many times did they ride their bikes in total?
[Answer]To find the number of total bike rides, we must first determine how many times John rode his bike. We do this by performing 17 * 2 = 34 times for John. Since John's mother rode 10 times more than John did, we find her total by performing 34 + 10 = 44 times. For all three people put together then, we perform 44 + 34 + 17 = 95 times in total. The answer is 95.
Q: Alice wants 1000 folded paper cranes. She folds half by herself, and a friend folds a fifth of the remaining paper cranes for her. How many paper cranes does Alice still need to fold?
A: Alice folds 1000 * 0.5 = 500 paper cranes by herself. This leaves 1000 500 = 500 paper cranes left to fold. A friend folds a fifth of the remaining amount, so they have folded 500 / 5 = 100 paper cranes for her. This means there is a total of 1000 500 100 = 400 paper cranes left for Alice to fold. The answer is 400.
Question: Lena is making a collage with pictures of all her closest friends and newspaper clippings that are about their interests. She has found three clippings for each friend's pictures. It takes her six drops of glue to stick down each clipping. Lena has already glued her seven closest friends' pictures. How many drops of glue will she need for the newspaper clippings for her collage?
Answer: Lena has 3 clippings per friend, so she has 3 * 7 = 21 clippings to glue. She needs 6 drops of glue per clipping, so she will need 6 * 21 = 126 drops of glue. The answer is 126.
[Question]A parking garage of a mall is four stories tall. On the first level, there are 90 parking spaces. The second level has 8 more parking spaces than on the first level, and there are 12 more available parking spaces on the third level than on the second level. The fourth level has 9 fewer parking spaces than the third level. If 100 cars are already parked, how many cars can be accommodated by the parking garage?
[Answer]The second level has 90 + 8 = 98 parking spaces. The third level has 98 + 12 = 110 parking spaces. The fourth level has 110 - 9 = 101 parking spaces. So the parking garage can accommodate 90 + 98 + 110 + 101 = 399 cars. Thus, the parking garage can still accommodate 399 - 100 = 299 cars. The answer is 299.
[Question]Ian won $100 in the lottery. He decided to use the money to pay off debts. He paid $20 to Colin. He then paid twice as much to Helen, as he had paid to Colin. Then finally, he paid half as much to Benedict, as he had paid to Helen. How much money, in dollars, does he have left after paying off debts?
[Answer]
Starting with $100, he paid $20 to Colin, leaving him with $100 - $20 = $80. Twice as much as $20 is 2 * $20 = $40. Thus, he paid $40 to Helen, leaving him with $80 - $40 = $40. Half as much to Benedict as he had paid to Helen is $40 / 2 = $20. Thus, he paid $20 to Benedict, leaving him with $40 - $20 = $20 after paying off all debts. The answer is 20.
