Final answer:
The race is 9,200 yards long.
Step-by-step explanation:
In a relay race, each team member runs the same distance. In this case, Jacob and the other 3 runners each run 2,300 yards. To find the total distance of the race, we need to multiply the distance run by one team member by the number of team members. So, the total distance of the race is 2,300 yards x 4 team members = 9,200 yards.
