Fran swims at a speed of 2.6 mph in still water. The Lazy River flows at a speed of 0.4 mph. How long will it take Fran to swim

BabaBlast [244]

Answer:

Upstream = 0.5 hour.

Downstream = 0.366 hour.

Step-by-step explanation:

Speed of fram in still water (u) = 2.6 mph.

Speed of water (v) = 0.4 mph .

<h3>Time taken by fran to swim 1.1 mi upstream.</h3>

Speed upstream = u - v = (2.6 - 0.4) mph = 2.2 mph

So the time taken = $\frac{distance}{speed} = \frac{1.1}{2.2}$ = 0.5 hour.

<h3>Time taken by fran to swim 1.1 mi downstream.</h3>

Speed downstream = u + v = (2.6 + 0.4) mph = 3 mph .

So the time taken = $\frac{1.1}{3}$ = 0.366 hour .
