Final answer:
The strider is performing Greece the distance (in miles) of the Joggers and Runners. Option c is correct.
Step-by-step explanation:
The strider is performing half the distance (in miles) of the Joggers and Runners, which is represented by the option C) Greece. This is because the Silk Road, a 4,000-mile route, was named for the costly silks that were acquired in China, indicating China as the starting point.
The question appears to be missing context, but if we assume it involves proportional reasoning or fractions, Greece, being roughly at the midpoint of the Silk Road, would imply that the strider is covering half the distance.
Looking at the data provided for runners' speeds, this seems not to relate directly to the strider's distance question but rather gives us an example of a comparison of speeds among runners.
Forty percent of runners ran at speeds less than or equal to 7.5 miles per hour, and sixty percent ran at speeds greater than 7.5 miles per hour. Although this may be part of a larger problem, it is not directly linked to the strider's distance in relation to the options given, which are countries.
Option c is correct.
