During an event, a hot air balloon traveled a distance of 5,110 feet during the first trip and 850 feet more during the second trip. How far did it travel during the second trip?

Question 1. What do I need to find?

Answer: We need to find the number of feet the balloon traveled during the second trip.

Question 2. What information do I need to use?

Answer: We will use the facts that the ballon traveled 5,110 feet during the first trip and 850 feet more during the second trip.

Question 3. How will I use the information?

Answer: We can draw a diagram or use a bar model to help me find how many feet the ballons traveled during the second trip.

Explanation: As hot air balloon traveled a distance of 5,110 feet in the first trip and 850 more in the second trip, so the second trip is 5,110+850= 5,960 feet. So, the balloon traveled 5,960 feet during the second trip.

Question 4. How far did it travel during the second trip? And ______ feet

Answer: The ballon traveled 5,960 feet during the second trip.

Question 5. Is your answer reasonable? Explain how you know.

Answer: Yes, the answer is reasonable.

Explanation: As 5,960 feet is reasonable because 5,000+1,000= 6,000 and 5,960 is close to 6,000. Since addition and subtraction are inverse operations, we can subtract 850 from the sum to see if we get 5,110.
