A river is flowing with a velocity = 4i m/s. A boat is moving with a velocity BR = (−2i + 4j) m/s relative to river. The width of the river is 100 m along y-direction. Match column I with column II (in SI units)

Column I Column II

(A) Velocity of boat w.r.t ground (P) 25 s

(B) Time taken to cross river (Q) 50 m

(C) Drift (R) √20 m/s
