A boat goes 30 km upstream and 44 km downstream in 10 hours the linear equation representing the situation graphically is:
Answers
Let speed of boat in still water be x km/h and speed of stream be y km/h.
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/h
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/hSpeed downstream= (x + y) km/h
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/hSpeed downstream= (x + y) km/hOn subtracting, we get,
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/hSpeed downstream= (x + y) km/hOn subtracting, we get,On solving, we get,
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/hSpeed downstream= (x + y) km/hOn subtracting, we get,On solving, we get,Speed of boat in still water = 8 km/h
Let speed of boat in still water be x km/h and speed of stream be y km/h.Speed upstream= (x - y) km/hSpeed downstream= (x + y) km/hOn subtracting, we get,On solving, we get,Speed of boat in still water = 8 km/hAnd, Speed of stream = 3 km/h
