Q1. A boat takes 12 hours to cover an upstream distance of 48 km and 6 hours to come back same distance in downstream. What is the speed of boat in steel water?
Q2. A swimmer can swim 33⅓% faster in downstream than in upstream. He takes 4 hours to swim a distance of 32 km in still water. Speed of stream is how much percent of upstream speed?
Q3. Rohit and Mohit are coming via boat towards each other from the two banks of a river. They meet after three hours from start. If speed of both boats in still water is 6 kmph and river is flowing from Mohit towards Rohit, then find the distance between two banks.
