Two ants race across a table 76 cm long. One

travels at 5.2 cm/s and the other at 2 cm/s.
When the first one crosses the finish line,
how far behind is the second one?
Answer in units of cm.
Can you teach me how to do this plz?

fast one takes t = 76/5.2 seconds

slow one goes d = 2(76/5.2)
so
76 - 2(76/5.2)
