To find the two runners who had a difference of 0.24 seconds between their finish times, we can compare the times:
- Jumarcus: 50.51 seconds
- Keyunta: 49.78 seconds
- Mica: 48.44 seconds
- Elijah: 50.02 seconds
Now, let's calculate the differences between the runners' times:
-
Keyunta and Mica:
- Difference: 49.78 - 48.44 = 1.34 seconds
-
Jumarcus and Keyunta:
- Difference: 50.51 - 49.78 = 0.73 seconds
-
Jumarcus and Elijah:
- Difference: 50.51 - 50.02 = 0.49 seconds
-
Keyunta and Elijah:
- Difference: 49.78 - 50.02 = 0.24 seconds (this fits the criteria)
-
Mica and Elijah:
- Difference: 48.44 - 50.02 = 1.58 seconds
The only pair of runners with a difference of 0.24 seconds is Keyunta and Elijah.
So the correct response is:
Keyunta and Elijah.
