Madhya Pradesh Police Exam Model Paper 4

Tips & Tricks
Given:
Distance between two places = 12 km
Time taken going upstream = 3 hours
Time taken going downstream = 2 hours
Formula used:
Speed = Distance/Time
Speed of stream =(d–u)/2
Where,
Downstream speed = d
Upstream speed = u
Given:
Let the speed of stream be S
Downstream speed
⇒d=12/2
⇒d=6 kmph
Upstream speed
⇒u=12/3
⇒u=4 kmph
Speed of stream
⇒S=(6–4)/2
⇒S=2/2
⇒ S = 1 kmph
∴ The speed of stream is 1 kmph
