A boat can cover a distance of 56 km downstream in 3.5 hours. The ratio of the boat in still water and the speed of stream is 3 : 1. How much time (in hours) will the boat take to cover a distance of 41.6 km downstream?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2.6.
Given:
A boat can cover a distance of 56 km downstream in 3.5 hours;
Formula used:
Speed = Distance/time
Calculations:
Speed of the boat downstream = 56/3.5 = 16 kmph
To cover the distance of 41.6 km downstream, time taken = 41.6/16 = 2.6 hours
Hence,
Time taken by the boat to cover 41.6 km downstream is 2.6 hours.
