5 word problems

 

Give me 5 word problems

1. Treasure Hunt: A pirate buried 3 chests along a beach, marked by flags spaced 5 paces apart. The first flag is 10 paces from a palm tree. If X marks the palm tree, find the location of each chest in terms of X.

2. Recipe Remix: A recipe uses 4 cups flour: 2 cups whole wheat, 1 cup spelt, and 1 cup all-purpose. You only have 3 cups total of whole wheat and spelt. What ratio of whole wheat and spelt should you use to maintain the original recipe's proportions?

3. Bridge Crossing: 3 cars can cross a bridge in 7 minutes. If each car takes 2 minutes to cross individually, how long does it take for all 3 cars to cross, assuming they cross one at a time?

4. Movie Marathon: You have 5 hours to watch movies. Your favorite movie is 2 hours long, and you want to watch at least 2 other movies of equal length. What is the maximum runtime of each other movie you can watch while still fitting in your favorite movie?

5. Coin Toss Challenge: You flip a coin 5 times. How many different sequences of heads and tails are possible?

These word problems cover different skill levels and mathematical concepts. If you have any preferences (arithmetic, geometry, probability, etc.), I can tailor the next set to your specific interests!

Problem Solutions with Explorations:

1. Treasure Hunt:

• The flags are spaced 5 paces apart, so the second flag is 10 + 5 = 15 paces from the palm tree.
• Similarly, the third flag is 15 + 5 = 20 paces from the palm tree.
• Therefore, the location of each chest in terms of X is:
  • First chest: X + 10 paces
  • Second chest: X + 15 paces
  • Third chest: X + 20 paces

2. Recipe Remix:

• You have 3 cups of whole wheat and spelt combined, and the original recipe used 2 cups of whole wheat and 1 cup of spelt in that ratio.
• To maintain the proportions, you need to use the same ratio of whole wheat to spelt, which is 2:1.
• Therefore, you should use 2/3 (66.67%) of your available mixture for whole wheat and 1/3 (33.33%) for spelt.

3. Bridge Crossing:

• Each car takes 2 minutes to cross individually, but the time it takes for all 3 cars to cross depends on whether they wait for each other.
• If they cross one at a time, the first car spends 2 minutes crossing, then the second car spends 2 minutes, and finally the third car spends 2 minutes.
• Therefore, the total time for all 3 cars to cross is 2 + 2 + 2 = 6 minutes.

4. Movie Marathon:

• You have 5 hours total and want to watch your favorite 2-hour movie.
• This leaves you with 5 - 2 = 3 hours for other movies.
• You want to watch at least 2 more movies of equal length, so these movies combined should take up less than 3 hours.
• Let x be the runtime of each other movie. You want to satisfy the inequality 2x < 3.
• Dividing both sides by 2 gives x < 1.5 hours.
• Therefore, the maximum runtime of each other movie you can watch is 1 hour 30 minutes while still fitting in your favorite movie.

5. Coin Toss Challenge:

• Each flip has two possibilities: heads (H) or tails (T).
• For 5 flips, each flip is independent, meaning the result of one doesn't affect the others.
• Therefore, the total number of possible sequences is 2 possibilities per flip raised to the power of the number of flips, which is 2^5 = 32.

These solutions offer concise answers while also providing explanations for the reasoning behind each step. Feel free to ask if you have any further questions or would like a deeper dive into any of these problems!
