This question is best answered by finding the least common multiple of both 45 and 20. If a scenario indicates every so many, it would be like listing the multiples. It can be harder to list the multiples of bigger numbers (45, 90, 135, 180 and 20, 40, 60, 80, 100, 120, 140, 160, 180), so another strategy is to use prime factorizations. The prime factorization of 45 is <em>3</em> x <em>3</em> x 5 and the prime factorization of 20 is <em>2</em> x <em>2</em> x 5. The numbers that are the same in both prime factorizations are part of your answer. All other numbers (the italicized ones) also become a factor in your final answer, so 5 x 3 x 3 x 2 x 2 = 180. This means 180 minutes later they both start again at the same time. So 3 hours from 9 am is 12 noon.

- <em>A=3120</em>
Hey You!
1. 5 - 8 / 5 × 100 = 60
From $5 to $8 is 60% increase.
2. 20 - 30 / 20 × 100 = 50
From 20 students to 30 students is a 50% increase.
3. 86 - 150 / 86 × 100 = 74.4186046511628 Round to 74.
From 86 books to 150 books is a 74% increase.
4. 3.49 - 3.89 / 3.49 × 100 = 11.461318051575958 Round to 11.
From $3.49 to $3.89 is 11% increase.
Answer:
it took the plane 5 hours to get there and now that you know the time it took for the plane to get there divide it by the miles which equals 300 miles per hour
