On Monday, if difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream is 15 hours, find the total time taken by the boat to go upstream and downstream.
Let the speed of boat be x km/hr. According to question, => [400/(x-3)] - [400/(x+3)] = 15 => x = 13 km/hr Total time taken = (400/10) + (400/16) = 65 hrs
