Hey there! :)
Answer:
The 2nd choice.
Step-by-step explanation:
Looking at the tables, we can eliminate those that do not show an increase, then a decrease in speed.
Table 1:
The speed goes from 45, 43, 41, 42, to 43. This shows a decrease, then an increase. This choice is incorrect.
Table 2:
The speed goes from 45, 47, 49, 48 to 47. This shows an increase, then a decrease. This choice is correct.
Table 3:
The speed goes from 45, 45, 45, 43, to 41. This shows a constant speed, until a final decrease. This choice is incorrect.
Table 4:
In this table, the speed goes from 45, 43, 41, 41 and ends at 41. This shows an initial decrease, then a constant speed. This is incorrect.
Therefore, only table 2 shows an increasing, then decreasing speed.
