The speed of the boat relative to the water is 3 m / s, and the speed of the river flow is 0.5 m / s. Determine the speed of the boat relative to the boy on the bank if the boat is sailing against the current of the river.
To find the speed of a given boat relative to the boy on the shore, we will use the formula: V = Vl – Vt.
Values of variables: Vl – speed of a given boat relative to the water (Vl = 3 m / s); Vt – river flow speed (Vt = 0.5 m / s).
Calculation: V = Vl – Vt = 3 – 0.5 = 2.5 m / s.
Answer: With respect to the boy on the shore, the given boat moves at a speed of 2.5 m / s.
