Answer:
16.55m/s
Step-by-step explanation:
If a child rows a rowboat north across a creek at 15 m/s and creek flows east at 7
m/s. the magnitude of the resultant velocity is gotten using pythagoras theorem as shown
R² = 15²+7²
R² = 225+49
R² =274
R = √274
R = 16.55m/s
Hence the magnitude of the resultant velocity is 16.55m/s
