Question

a car increases, then decreases, its speed. which table could represent the speed of the car?

Explanation:

Step1: Analyze speed - change condition

The car's speed first increases then decreases.

Step2: Check each table

In the first table, speed decreases continuously (45 - 43 - 41 - 41 - 41). In the second table, speed is constant at 45 for first 3 time - intervals and then decreases. In the third table, speed increases (45 - 47 - 49 - 48 - 47). In the fourth table, speed first increases (45 - 43 - 41 - 42 - 43), which meets the requirement of increasing then decreasing.

Answer:

The fourth table.
