The width of river is 1 km. The velocity of boat is 5 km/hr. The boat covered the width of river along the shortest path in 15 min. Then the velocity of river stream is

  1. 3 km/hr
  2. 4 km/hr
  3. 29 km/hr
  4. 41 km/hr

Answer

(1) 3 km/hr

Solution

For the shortest path, the resultant velocity is perpendicular to the stream.

Resultant speed = 1 km 1560 hr = 4 km/hr

vboat2 = vresultant2 + vriver2

vriver = 52 - 42

= 3 km/hr
