Problem Statement
A boat in upstream can travel 5 km in 30 minutes. If the speed of the stream is 1.5 kmph, then find the total distance covered by the boat when it takes 46 hours to travel from A to B and return.
Explanation
Upstream speed = 5 km / 0.5 hr = 10 km/h → boat speed = 11.5 km/h. Let distance = D. D/13 + D/10 = 46 → D = 260. Total = 520 km.
