Final answer:
The student has gone almost exactly 2.3 kilometers by walking up and down the length of a soccer field twenty times.
Step-by-step explanation:
The student has walked up and down the length of a soccer field twenty times. To find out how far they have gone, we need to know the length of the soccer field. The question does not provide this information, so we cannot determine the exact distance. However, we do know that soccer fields vary in size, and a large soccer field has dimensions of 115 meters long and 85 meters wide.
If we assume that the student is walking the length of this large soccer field, they would have covered a distance of 115 meters per walk. Since they have walked 20 times, we can calculate the total distance as:
Total Distance = 115 meters/walk x 20 walks = 2300 meters
Therefore, the student has gone almost exactly 2.3 kilometers.
