Answer:

given relative speed of boat = 15km/hr

speed of river = 5km/hr

therefore, speed of boat = 15+5 = 20km/hr

total speed of boat = 25km/hr ( as the boat and the river are moving in the same direction and the boat is riding on the river , with perspective to one standing on land , he will see the boat move at a speed of 5+20km/hr.)

total time = 3hr

distance covered = 3 × 25 = 75km

hope it will help
