Identifying Constant RateQuestion 1 of 1

A delivery truck's distance from its starting point is recorded every hour. The data shows: Hour 1: 45 miles, Hour 2: 90 miles, Hour 3: 135 miles, Hour 4: 160 miles, Hour 5: 185 miles. Sarah claims the truck traveled at a constant rate for the entire trip. Which analysis correctly evaluates her claim?

Sarah is correct because the truck's distance from start increases every hour consistently
Sarah is incorrect because the rate was 45 mph for hours 1-3, then 25 mph for hours 4-5
Sarah is incorrect because the rate was consistent for hours 1-3 but decreased significantly afterward
Sarah is correct because the average rate over the entire trip represents constant motion

Question 1

A delivery truck's distance from its starting point is recorded every hour. The data shows: Hour 1: 45 miles, Hour 2: 90 miles, Hour 3: 135 miles, Hour 4: 160 miles, Hour 5: 185 miles. Sarah claims the truck traveled at a constant rate for the entire trip. Which analysis correctly evaluates her claim?

  1. Sarah is correct because the truck's distance from start increases every hour consistently
  2. Sarah is incorrect because the rate was 45 mph for hours 1-3, then 25 mph for hours 4-5
  3. Sarah is incorrect because the rate was consistent for hours 1-3 but decreased significantly afterward (correct answer)
  4. Sarah is correct because the average rate over the entire trip represents constant motion
Explanation: To evaluate constant rate, we calculate the rate of change between consecutive hours. Hours 1-2: (90-45)÷1 = 45 mph. Hours 2-3: (135-90)÷1 = 45 mph. Hours 3-4: (160-135)÷1 = 25 mph. Hours 4-5: (185-160)÷1 = 25 mph. The rate is constant at 45 mph for hours 1-3, then decreases to a constant 25 mph for hours 4-5. This shows two different constant rates, not one constant rate throughout.
