Let's solve each problem step by step and identify the "trick" problem that is not a multiplication problem.
---
Problem 1:
A foot is about 30 cm. A basketball court is 50 ft wide. How many cm wide is this? How many meters wide?
#### Step 1: Convert feet to centimeters.
- 1 foot = 30 cm
- Basketball court width = 50 ft
\[
\text{Width in cm} = 50 \times 30 = 1500 \, \text{cm}
\]
#### Step 2: Convert centimeters to meters.
- 1 meter = 100 cm
- Width in meters:
\[
\text{Width in m} = \frac{1500}{100} = 15 \, \text{m}
\]
Answer:
- Width in cm: \( \boxed{1500} \)
- Width in m: \( \boxed{15} \)

Problem 2:
A sailfish can swim at speeds of 31 meters per second. How far could it travel in 25 seconds at this speed?
#### Step 1: Use the formula for distance.
\[
\text{Distance} = \text{Speed} \times \text{Time}
\]
- Speed = 31 m/s
- Time = 25 s
\[
\text{Distance} = 31 \times 25 = 775 \, \text{m}
\]
Answer:
\( \boxed{775} \) meters

Problem 3:
A pint is 568 ml. How many ml in a gallon?
#### Step 1: Understand the conversion.
- 1 gallon = 8 pints
- 1 pint = 568 ml
\[
\text{Volume in ml} = 8 \times 568 = 4544 \, \text{ml}
\]
Answer:
\( \boxed{4544} \) ml

Problem 4:
A pair of scissors costs $2.59. How much would 6 pairs cost at this price?
#### Step 1: Calculate the total cost.
- Cost of 1 pair = $2.59
- Number of pairs = 6
\[
\text{Total cost} = 2.59 \times 6 = 15.54 \, \text{dollars}
\]
Answer:
\( \boxed{15.54} \) dollars
---
Problem 5:
An M&Ms chocolate packet contains 36 chocolate sweets. How many sweets in a multipack bag of 15 packets?
#### Step 1: Calculate the total number of sweets.
- Sweets per packet = 36
- Number of packets = 15
\[
\text{Total sweets} = 36 \times 15 = 540
\]
Answer:
\( \boxed{540} \) sweets
---
Problem 6:
There are on average 154 words on each page of the book ‘How to Look after your Salamander’. The book contains 12 pages. How many words are there in the book?
#### Step 1: Calculate the total number of words.
- Words per page = 154
- Number of pages = 12
\[
\text{Total words} = 154 \times 12 = 1848
\]
Answer:
\( \boxed{1848} \) words
---
Problem 7:
A cruise ship travels at 22 miles per hour. How many hours will it take to make a 132 mile journey?
#### Step 1: Use the formula for time.
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]
- Distance = 132 miles
- Speed = 22 mph
\[
\text{Time} = \frac{132}{22} = 6 \, \text{hours}
\]
Answer:
\( \boxed{6} \) hours

Identifying the Trick Problem:
The trick problem is
Problem 7, as it involves division rather than multiplication. All other problems require multiplication to solve.
---
Final Answers:
1. Width in cm: \( \boxed{1500} \), Width in m: \( \boxed{15} \)
2. Distance traveled: \( \boxed{775} \) meters
3. Volume in a gallon: \( \boxed{4544} \) ml
4. Total cost of 6 pairs of scissors: \( \boxed{15.54} \) dollars
5. Total sweets in a multipack: \( \boxed{540} \)
6. Total words in the book: \( \boxed{1848} \)
7. Time for the journey: \( \boxed{6} \) hours
The trick problem is
Problem 7.
