Solution:

Use the RTD formula:

{125 \meters}/{\second}

x (# of seconds traveled) > 2 kilometers. Convert kilometers to meters:

{125 \meters}/{\second}

x (# of seconds traveled) >2,000 meters → # of seconds traveled >

{2000}/{125}

→ # of seconds traveled > 16.16 seconds >

1/4

of a minute. Thus, Quantity A is greater.
