In a 24 km race, during which each runner maintains a constant speed throughout, alice crosses the finish line while becky is still 8 km from finishing and caitlin is 12 km from finishing. when becky crosses the finish line, caitlin still has d kilometers to go. find all possible values of d.

6km

Step-by-step explanation:

Given

when Alice finishes the race Becky is 8km From finishing line

and caitlin 12 km from finishing line.

Suppose t is the time require by Alice to finish the race

and be the velocity of alice ,becky and caitlin

thus

thus

say t' is time required by beckey  to complete 8 km thus

therefore for Caitlin

Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
