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

What is speed?

  • 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;

[tex]v = \frac{d}{t} \\\\v = \frac{100 \ m}{28 \ s}\\\\v = 3.57 \ m/s\\\\v \approx 3.6 \ m/s[/tex]

Thus, the speed of the stream's current is 3.6 m/s.
