Question

# A bird is at a point ( P(4,-1,-5) ) and sees two points ( P_{1}(-1,-1,0) ) and ( P_{2}(3,-1,-3) . ) At time ( t=0, ) it starts flying with a constant speed of ( 10 mathrm{m} / mathrm{s} ) to be in line with points ( mathrm{P}_{1} ) and ( mathrm{P}_{2} ) in minimum possible time t. Find ( t ), if all coordinates are in kilometers.
