Hi Megan;
distance=(27.6 meters/second)(8.1 seconds)
The unit of seconds is in the numerator and denominator.  Therefore, these cancel...
distance=(27.6 meters/second)(8.1 seconds)
distance=(27.6 meters)(8.1)
Now that the units are aligned, we may calculate.
distance=223.56 meters
Distance = Speed * Time
D = (27.6 m/s) * (8.1s)
D = (27.6 * 8.1) * (m*s/s)
D = 223.56 m
