Answer» Step-by-step explanation:LET the speed of boat in still water be X km/hr and the distance be y km. Speed in downstream = (x + 2) km/hr Speed in upstream = (x − 2) km/hrAccording to the question, ( Speed formula ) --------> (1) ( Speed formula ) --------> (2)On modifying (1) we get, y = 5(x+2) ---------> (3)On substituting (3) in (2) we get,5x + 10 = 6(x - 2)5x + 10 = 6x - 125X - 6x = -12 - 10-x = -22∴ x = 22Hence, the speed of the boat in still water will be 22 km/hrHOPE YOU LIKED MY ANSWER!!PLEASE MARK ME AS BRAINLIEST!!THANK YOU!! |
