The formula to calculate distance is:

\[ \text{Speed (km/h)} = \frac{\text{distance (km)}}{\text{time (h)}} \]

\[ \text{Pace (sec/km)} = \frac{\text{time (sec)}}{\text{distance (km)}} \]

Where:

• \(\text{Speed}\) is the speed in kilometers per hour (km/h).
• \(\text{Pace}\) is the time per kilometer (sec/km).
• \(\text{Time}\) is the total time taken (hours or seconds).
• \(\text{Distance}\) is the total distance covered (km).
