Answer: Alberto run 27 meters.

Time taken By Alberto=3 seconds


Step-by-step explanation:

Let d be the distance Alberto ran to catch Omar.

Then, distance ran by Omar=x-6

Also, \text{Time}=\frac{\text{Distance}}{\text{Speed}}

Since, both started running at the same time.

Time taken By Alberto=\frac{x}{9}

Time taken By Omar=\frac{x-6}{7}

Now, at the point they meet time taken by both is equal.

\frac{x}{9}=\frac{x-6}{7}\\\Rightarrow\ 7x=9(x-6)\\\Rightarrow7x=9x-54\\\Rightarrow9x-7x=54\\\Rightarrow\ 2x=54\\\Rightarrow\ x=27

Hence, Alberto run 27 meters.

Time taken By Alberto=\frac{27}{9}=3 seconds
