krok68 [10]
Divergent evolution is when two different species share the same ancestral origins but have evolved differently whereas convergent evolution is when species with different ancestral origins have developed similar features.

Illusion [34]

The correct answer is A. 20.2 s

Explanation:

The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:

20 + 19.2 + 21.5 = 60.7 - Results of each of the trials

60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials

This means the average time for the toy to move on dirt was 20.2s
