Question

A bird is at a point 'P' whose coordinates are (4m,-1m,; m) . The bird observes two points P 1 and P 2 having coordinates (- 1m, 2m, 0m) and (1m, 1m, 4m) respectively. At time t = 0 , it starts flying in a plane of three positions, with a constant speed of 5 m/s in a direction perpendicular to the straight line P 1 P 2 till it sees P 1 and P 2 collinear at time t^ prime . Calculate 't'​
