# Answer to Question #72955 in Other Physics for Chloe Willig

Question #72955

Two boats are sailing directly toward each other at different speeds. One moves at 20m/s while the other at 32m/s. The boats start 2,500 m apart. How much time does it take before the boats collide?

Expert's answer

The velocity of the boats relative to each other

v=v_1+v_2=20+32=52 m/s

So, the time when the boats would collide

t=L/v=2500/52=48 s

v=v_1+v_2=20+32=52 m/s

So, the time when the boats would collide

t=L/v=2500/52=48 s
