The speed of the stream's current is 3.6 m/s.
The given parameters:
- distance between the two flags, d = 100 m
- time when it passed the first flag, t₁ = 2:15
- time when it passed the second flag, t₂ = 2:43
- The speed of an object describes the rate of change of an object's distance.
The change in the time of motion of the barrel is calculated as follows;
Δt = t₂ - t₁
Δt = 2:43 - 2:15
Δt = 2 min 43 s - 2 min 15 s
Δt = 43 s - 15 s
Δt = 28 s
The speed of the stream's current is calculated as follows;
Thus, the speed of the stream's current is 3.6 m/s.
