Show answer and solution

Correct answer: A. 1 hour 15 minutes

1. Upstream speed = 2 km/h; downstream speed = 1 km in 10 min = 6 km/h. 2. Speed in still water = (downstream + upstream)/2 = (6 + 2)/2 = 4 km/h. 3. Time for 5 km = 5/4 h = 1.25 h = 1 hour 15 minutes. _Source: RRB Group D (RRC) PYQ, held 27-10-2013, Q.48._
