Answer: 1,875 days
Solution: First, we need to know how many pounds of peach the friends are eating. Since a ton is 2,000 pounds, 8 tons is 16,000 pounds. The peach pit weighs half a ton, which is 1,000 pounds, so the friends eat a total of 15,000 pounds of peach. In total, they eat 8 pounds of peach per day, so we divide 15,000 ÷ 8 to find that it will take them 1,875 days to eat the whole peach.
Answer: 25 miles per hour
Solution: Since the seagulls’ speed is slowed by 5 miles per hour, we can represent their slowed speed as (x – 5) if x is the speed they fly in still conditions. Since “distance = rate × time,” we can set up this equation:
260 = (x – 5) × 13
When we solve for x, we get 25 miles per hour.
