Final answer:
Jada's long distance race is a total of 20 kilometers. This is determined by dividing the 3 km she ran by the 15% it represents and then multiplying by 100.
Step-by-step explanation:
To determine the total distance of Jada's long distance race, we can start by understanding that the 3 km she ran is 15% of the total distance. To find the full distance, we can divide the distance she ran by the percentage this represents of the total, and then multiply by 100 to find the full 100%.
Calculation: Total Distance (100%) = (Distance ran ÷ Percentage of total) × 100
Total Distance = (3 km ÷ 15) × 100 = 20 km
Therefore, the total distance of Jada's long distance race is 20 kilometers.
