Question
A boat's speed in calm water exceeds the speed of the
current by 12 km/hr. Given that the current's speed is 1.25x km/hr and the boat takes 5 hours to travel 160 km downstream, determine the value of ‘x’.Solution
According to the question, 1.25x + 1.25x + 12 = 160/5 Or, 2.5x = 20 Or, x = 8
