Question

A boat travels the same distance 'd' km in both upstream and downstream directions, taking a total of 15 hours for the round trip. If the downstream speed of the boat is 16 km/hr and the upstream speed is 8 km/hr, calculate the time required for the boat to cover '1.5d' km in still water.
