The distance traveled by the canoe in the water is 0.93 m.

The given parameters;

Apply the principle of conservation of linear momentum to determine the distance traveled by the canoe;

$m_1v_1 = m_2 v_2\\\\m_1(\frac{d_1}{t} ) = m_2(\frac{d_2}{t} )\\\\4(4.9) = 21(d_2)\\\\d_2 = \frac{4(4.9)}{21} \\\\d_2 = 0.93 \ m$

Thus, the distance traveled by the canoe in the water is 0.93 m.
