Thank you for the opportunity to help you with your question!

Total runners = 72

Runners dropped in the first half= (1/3) of 72 =(1/3)*72= 24

Runners remaining for second half = 72 - 24 = 48

Runners dropped in the second half = (2/3) of 48= (2/3)*48= 32

Therefore,

Runners who finished the race = 48 - 32 = 16

Please let me know if you need any clarification. I'm always happy to answer your questions.
