The speed of the boat downstream is 23.7 km / h. Find your own speed of the boat and its speed against the current, if the current speed is 3.8 km / h.
To find the boat’s own speed, it is necessary to subtract the current speed from its downstream speed.
V = V1 – Vt, where V1 is the speed of the boat downstream (V1 = 23.7 km / h), Vt is the speed of the current (Vt = 3.8 km / h).
V = V1 – Vt = 23.7 – 3.8 = 19.9 km / h.
To find the speed of the boat against the current, it is necessary to subtract the speed of the current from its own speed downstream.
V2 = V – Vt = 19.9 – 3.8 = 16.1 km / h.
Answer: The boat’s own speed is 19.9 km / h, the speed of the boat against the current is 16.1 km / h.
