The correct Answer is:
To solve the problem, we need to find out how far a person can travel in 5 hours if they travel \(10 \frac{1}{5}\) km in 3 hours. Let's break it down step by step. ### Step 1: Convert the mixed fraction to an improper fraction The distance traveled is given as \(10 \frac{1}{5}\) km. We can convert this mixed number into an improper fraction. \[ 10 \frac{1}{5} = 10 + \frac{1}{5} = \frac{50}{5} + \frac{1}{5} = \frac{51}{5} \text{ km} \] **Hint:** To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. ### Step 2: Calculate the distance traveled in 1 hour Now, we need to find out how much distance is covered in 1 hour. Since the person travels \(\frac{51}{5}\) km in 3 hours, we can find the distance per hour by dividing the total distance by the total time. \[ \text{Distance in 1 hour} = \frac{\frac{51}{5} \text{ km}}{3 \text{ hours}} = \frac{51}{5} \times \frac{1}{3} = \frac{51}{15} \text{ km} \] **Hint:** To find the distance per hour, divide the total distance by the total time. ### Step 3: Calculate the distance traveled in 5 hours Next, we need to find out how far the person travels in 5 hours. We can do this by multiplying the distance traveled in 1 hour by 5. \[ \text{Distance in 5 hours} = \frac{51}{15} \times 5 = \frac{51 \times 5}{15} = \frac{255}{15} = 17 \text{ km} \] **Hint:** To find the total distance for a different time period, multiply the distance per hour by the number of hours. ### Conclusion The distance covered by the person in 5 hours is **17 km**. **Final Answer:** 17 km (Option B) ---
