A runner starts a 5km race but after 750m, he increases his pace and runs at twice his initial speed. If he completes the race in 14 minutes, how many minutes did it take him to cover the first 750m?	The race distance was 5000m. He covered 750m with his initial speed. So, the distance he covered with the double speed is 5000 - 750 = 4250m. If he covered this distance in 14 minutes, then he covered the first 750m in 14-x minutes. Since he ran the 4250m part at double speed, he would have taken 2(14 - x) minutes to cover that distance running at his initial speed. So, the total time would be equal if he ran at his initial speed: 750m takes x minutes and 4250m takes 2(14 - x) minutes. Solving this, 750x = 42502(14 - x), it simplifies to 3750 = 59x So, x = 3750/59 = 63.55 minutes. So, he covered the first 750m in approximately 64 minutes	64

Tom decided to organize his books. He has 3 times as many novels as biographies, and he has twice as many biographies as science books. If the total number of books he has is 30, how many science books does he have?

Let n be the number of novels, b the number of biographies and s the number of science books. We know that n + b + s = 30, n = 3b and b = 2s. Substitute the second and third equations into the first one, we get 3b + b + 1/2b = 30 Combining like terms, we get 4.5b = 30 Dividing both sides by 4.5, we get b = 30 / 4.5 = 6.66 which means he has 7 biographies Since he has twice as many biographies as science books, s = b / 2 = 3.5 which means he has 4 science books

A runner starts a 5km race but after 750m, he increases his pace and runs at twice his initial speed. If he completes the race in 14 minutes, how many minutes did it take him to cover the first 750m?

The race distance was 5000m. He covered 750m with his initial speed. So, the distance he covered with the double speed is 5000 - 750 = 4250m. If he covered this distance in 14 minutes, then he covered the first 750m in 14-x minutes. Since he ran the 4250m part at double speed, he would have taken 2*(14 - x) minutes to cover that distance running at his initial speed. So, the total time would be equal if he ran at his initial speed: 750m takes x minutes and 4250m takes 2*(14 - x) minutes. Solving this, 750x = 4250*2*(14 - x), it simplifies to 3750 = 59x So, x = 3750/59 = 63.55 minutes. So, he covered the first 750m in approximately 64 minutes

Combining like terms, we get 5r = 80. Dividing both sides by 5, we get r = 16. Substituting this value into s = 4r, we find that s = 4 * 16 = 64.
