- Homework Statement
- How far from its original position is the boat now?

- Relevant Equations
- With reference to ground, the water travels downstream for 2.5+3.5= 6 hours.

With reference to water, the boat went upstream for 1 hour. So the boat is

10/3×6−15/2×1=12.5 km downstream from the start.

A boat goes upstream for 3 hr 30 min and then goes downstream for 2 hr 30 min. If the speed of the current and the speed of the boat in still water are 10/3 kmph and 15/2 kmph respectively, how far from its original position is the boat now?

Final Equation: 10/3×6−15/2×1=

Why should we solve this question through references?

How boat went upstream for 1 hour if question clearly says boat goes upstream for 3 hr 30 min?
