Condition 2: When Two Person With Speed S1 Km/hour And S2 Km/hour, Starting With A Same Position On The Circumference Of Track C Km In Opposite Direction:
A.Time Taken For Meeting First Time At Any Position: (C/S1+S2) Hour
B.Time Taken For Meeting At Starting Point, At First Time:
LCM(C/S1.C/S2)hour.
Notes1.We Can Use The Concept Of Time  Speed And Distance For Convering Km/hour To Metre/ Second Or Vice Versa
Notes2: When We Consider Sign Of Above Formula Then This Is Same As Rail Problem.

Boats And Streams Problems In Aptitude For Competitive Exams


Boats And Stream Problems In Aptitude For Competitive Exams Like CAT, SSC, IBPS Bank PO, IAS, Gate And Other Government Exams.

Concepts On Boats And Streams Problem:
1.When Boat And Water Stream Move In One Direction Then This Is Called Boat Is Moving Downstream.The Total Speed Of Boat Would Increased In This Condition.
2.When Boat And water Stream Are Moving In Opposite Direction Then Boat Is Called Moving Upstream.The Total Speed Of Boat Would Decreased In This Condition.
Let, Speed Of Boat In Constant Water = S1
Speed Of Water Stream = S2

Formula1: Speed Of Boat In DownStream Condition = (S1+S2)Km/hour

Formula2: Speed Of Boat In Upstream Condition = (S1-S2)Km/hour

Notes: This Is The Advice Of Author To Learn The Formula. When We Concentrate On the Sign Of Above Formulas, These Are Different From Rail Problems.In First Formula water Stream And Boat Is in Same Direction But Sign Is + Not Minus Like Rail Problems.
This Is The Key For Learning These Formulas And Remove Confusion About These Problems.
Important Formulas:
If We Take Speed In Downstream Condition = S1 Km/hour
Speed In upstream Condition = S2 Km/hour
  • Speed In Constant Water = 1/2(S1+S2) Km/hour.
  • Rate Of Stream: 1/2(S1-S2) km/hour.
