a car increases, then decreases, its speed. which table could represent the speed of the car?
Answer
Explanation:
Step1: Analyze the first table
Check the speed values: (45,43,41,42,43). The speed first decreases ((45\to43\to41)) then increases ((41\to42\to43)), which is not “increase then decrease”.
Step2: Analyze the second table
Check the speed values: (45,47,49,48,47). The speed first increases ((45\to47\to49)) then decreases ((49\to48\to47)), which matches “increase then decrease”.
Step3: Analyze the third table
Check the speed values: (45,45,45,43,41). The speed is constant ((45,45,45)) then decreases ((45\to43\to41)), which is not “increase then decrease”.
Step4: Analyze the fourth table
Check the speed values: (45,43,41,41,41). The speed only decreases ((45\to43\to41)), which is not “increase then decrease”.
Answer:
The second table (with speed values (45,47,49,48,47))
