QuestionWhich situation shows a constant rate of change? A. Child's teeth vs. age B. Juice bottles vs. day C. People in arena vs. time D. Run distance vs. laps.
Studdy Solution
STEP 1
Assumptions1. The number of teeth a child has compared with her age changes at a non-constant rate because children grow teeth at different rates at different ages.
. The number of bottles of orange juice in a grocery store compared with the day of the month changes at a non-constant rate because it depends on the delivery schedule and customer purchases.
3. The number of people inside a basketball arena compared with the amount of time since the arena opened changes at a non-constant rate because people arrive and leave at different times.
4. The distance of a run compared with the number of times around a track changes at a constant rate because each lap around the track is a fixed distance.
STEP 2
Based on these assumptions, the situation that is most likely to have a constant rate of change is the distance of a run compared with the number of times around a track.
The solution is D. The distance of a run compared with the number of times around a track.
