Answer:

4 [miles].

Step-by-step explanation:

1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)

t_{us}+t_{ds}=5;

2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:

\frac{D}{V_{us}} +\frac{D}{V_{ds}} =5; \ (V_{us}-rowing \ upstream,V_{ds}-rowing \ downstream);

3) finally,

D=\frac{5V_{us}*V_{ds}}{V_{us}+V_{ds}};

D=5*4/5=4 [miles].

What is the solution to x?​
Sonja [21]

Answer:

Step-by-step explanation:

By geometric mean theorem,

In a triangle ABC,

\frac{BC}{AC}=\frac{CD}{BC}

\frac{y}{(4+6)}=\frac{6}{y}

y² = 60

y = √60

y = 7.75

Similarly, \frac{AB}{AC}=\frac{AD}{AB}

\frac{x}{(4+6)}=\frac{4}{x}

x² = 40

x = √40

x = 6.32
