The race is 123.90 meters long.

Since the next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart, if there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line, to determine how long is the race, the following calculation must be performed:

  • 8 x 12.30 + 15 + 10.5 = X
  • 98.4 + 25.5 = X
  • 123.90 = X

Therefore, the race is 123.90 meters long.
