Question

A swimmer is capable of swimming 1.65 mr
in still water. If she swims directly across
180m wide river whose current is 0.85 m/s
how far downstream (from a point opposite
her starting point) will she reach​

Answer 1

Answer:

Explanation:

Downstream means with the flow of water

So, swimmer's speed = his own speed+speed of current

=1.65+0.85

=2.5m/s

Time taken to swim across the river=distance/speed

=180/2.5

=72 seconds

Or 1 minute 12 seconds
