Dec 18, �� Example 19 A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours, it can go 40 km upstream and 55 km down-stream. Determine the speed of the stream and that of the boat in still water. Let the speed of boat in still water be x km/hr & let the speed of stream be y . Downstream. In the river-boat problems, we make some myboat123 boatplans assumptions are more like axioms that we have for
Upstream And Downstream Questions Class 10 Not these problems. A stream or a river can flow in one direction only. It goes either up (opposite to the direction of our boat) or down (in the same direction
Class 10 Upstream Downstream Questions Guide as the direction in which our boat travels). The speed or the velocity of the stream remains constant at all points. Pair of Linear Equations in Two Variables Class 10 Extra Questions Short Answer Type 2. Question 1. Solve: ax + by = a � b and bx � ay = a + b. Solution: The given system of equations may be written as. A boat covers 25 km upstream and 44 km downstream in 9 hours. Also, it covers 15 km upstream and 22 km downstream in 5 hours.
