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

Time taken by a boat to cover 90 km upstream is 2.5 hours more than that of same distance cover in downstream. If the ratio of Speed of boat in still water to stream is 5 : 1, then find the still water speed of the boat (in km/hr)?
The upstream speed of a boat is 15 km/hr and the ratio of time taken by the boat to cover 105 km upstream and 108 km downstream 7 : 6 respectively. Find the speed of stream (in km/hr)?
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?
