To find the two runners that had a finish time difference of 0.24 seconds, we can calculate the time differences between every pair of runners:
-
Keyunta (49.78) and Mica (48.44):
Difference = 49.78 - 48.44 = 1.34 seconds -
Keyunta (49.78) and Jumarcus (50.51):
Difference = 50.51 - 49.78 = 0.73 seconds -
Keyunta (49.78) and Elijah (50.02):
Difference = 50.02 - 49.78 = 0.24 seconds -
Mica (48.44) and Jumarcus (50.51):
Difference = 50.51 - 48.44 = 2.07 seconds -
Mica (48.44) and Elijah (50.02):
Difference = 50.02 - 48.44 = 1.58 seconds -
Jumarcus (50.51) and Elijah (50.02):
Difference = 50.51 - 50.02 = 0.49 seconds
The only pair with a difference of 0.24 seconds is Keyunta and Elijah.
So, the correct answer is: Keyunta and Elijah.
