Answer 1

The faster average among the 2 runner at the first 9 seconds can be computed below.

Runner A average

$\text{average sp}eed=\frac{dist}{\text{time}}=\frac{120}{9}=\frac{40}{3}\text{ m/s}$

Runner B average

$\text{average sp}eed=\frac{dist}{\text{time}}=\frac{120}{9}=\frac{40}{3}\text{ m/s}$

Therefore, runner A and B are tied .
