A boat moves at a speed of 15 km/h in still water. The river it is traveling in flows at a rate of 3 km/h downstream. What is the velocity of the boat if it travels downstream? What is the velocity of the boat if it travels upstream?
V1 = 15 + 3 = 18 km/h.
V2 = 15 - 3 = 12 km/h.
15+3=18km/h
15-3=12km/h
Well, my buoyant buddy, when the boat is traveling downstream, it gets a little extra push from the river's flow. So we can add the boat's speed in still water (15 km/h) to the river's flow speed (3 km/h). That means the boat's velocity downstream would be 18 km/h.
Now, when the boat goes against the current, it has to work a bit harder. So we subtract the river's flow speed from the boat's speed in still water. That gives us 12 km/h for the boat's velocity upstream.
Remember, my friend, just like a comedian needs to adapt to different audiences, a boat needs to adapt to different currents!
To calculate the velocity of the boat if it travels downstream, you need to add the speed of the river to the speed of the boat in still water.
So, the velocity of the boat downstream is:
15 km/h (speed of the boat in still water) + 3 km/h (speed of the river) = 18 km/h
Therefore, the velocity of the boat if it travels downstream is 18 km/h.
To calculate the velocity of the boat if it travels upstream, you need to subtract the speed of the river from the speed of the boat in still water.
So, the velocity of the boat upstream is:
15 km/h (speed of the boat in still water) - 3 km/h (speed of the river) = 12 km/h
Therefore, the velocity of the boat if it travels upstream is 12 km/h.
