Answer:
The table that best represent the speed of the car is:
Time 5 6 7 8 9
speed 45 47 49 48 47
Step-by-step explanation:
We are given a condition that the car first increases, and then decreases it's speed.
1)
Time 5 6 7 8 9
speed 45 43 41 42 43
In this the speed is first decreasing and then increasing.
Hence, this table is not the correct table.
2)
Time 5 6 7 8 9
speed 45 47 49 48 47
The speed is first increasing( Since it changes from 45 to 47 and then to 49) and then it decreases ( as it decreases from 49 to 48 and 48 to 47)
Hence, this is the correct table.
3)
Time 5 6 7 8 9
speed 45 45 45 43 41
The speed first remains constant and then it decreases.
Hence, this table is inaccurate.
4)
Time 5 6 7 8 9
speed 45 43 41 41 41
The speed first decreases and then it remains constant.
Hence, this table is not the correct table.
