The resultant velocity of the canoe is 2.88 m/s.
The Resultant velocity of the river can be calculated using Pythagoras Theorem
Pythagoras Theorem:
In a right angle triangle, The square of the hypotenuse is equal to the sum of the square of the two other sides.
Note: In a cardinal point, The north and the east are at right angle.
Formula:
- a² = b²+c²............... Euqation 1
Where:
- a = resultant velocity of the canoe
- b = speed of the canoe
- c = velocity of the flowing river.
From the question,
Given:
Substitute these values into equation 1
- a² = 2.4²+1.6²
- a² = 5.76+2.56
- a² = 8.32
- a = √8.32
- a = 2.88 m/s
Hence, the resultant velocity of the canoe is 2.88 m/s
