Speed of a boat in still water Is 10 km/hr. If speed of stream is 2 km/hr, then how much distance can the boat travel downstream in 2.5 hours?
Given:
Speed of a boat in still water = 10 km/hr
Speed of stream = 2 km/hr
Formula Used:
Downstream speed = Speed of a boat in still water + Speed of stream
Solution:
Downstream speed = 10 + 2 = 12 km/hr
In 1-hour boat travels = 12 km
Then, in 2.5 hours boat will travel = 2.5 × 12 = 30 km

Speed of a boat in still water Is 10 km/hr. If speed of stream is 2 km/hr, then how much distance can the boat travel downstream in 2.5 hours?
A man takes 13 hours to swim 91 km downstream. He swims 39 km upstream in the same time. What is the speed (in km/hr) of the boat in still water?
The speed of a boat in still water is 17 km/hr and the speed of the stream is 16 km/hr. A man rows to a place at a distance of 26.4 km and comes back to the starting point. Find the total time (in hours) taken by him.
