A small motor boat can travel downstream at a distance of 72 miles in 3 hours. The return trip against the current takes 4 hours. Find the speed of the cujrrent and the rate of the boat? The table I have is Rate Time and Distance...I am totally lost on this
let speed of boat= X mph sped of current= Y mph As per question 3(X+Y)=72 and 4(X-Y)=72 hence 3X+3Y=4X-4Y ⇒ X=7Y Substituting value of X we get⇒ 24Y=72 ⇒ Y=3 and X=7×3=21 Speed of current is 3 mph and boat is 2 mph
