If two objects travel through space along two different curves, it's often important to know whether they will collide.

will a missile hit its moving target? will two aircraft collide?

the curves might intersect, but we need to know whether the objects are in the same position at the same time.

suppose the trajectories of two particles are given by the vector functions for t 0. do the particles collide?

if they collide find t.

Which ratio is equivalent to 10: 85

Could someone me with this question i’ve been stuck on it for 20 minutes
