Juliette [100K]

Answer:

$15.75

Step-by-step explanation:

\frac{y}{15} :\frac{5}{100}

y × 100 = 5 × 15

100y = 75

100y ÷ 100 = 75 ÷ 100

y = 0.75

$15 - $0.75

$14.25

\frac{y}{15} :\frac{10}{100}

y × 100 = 10 × 15

100y = 150

100y ÷ 100 = 150 ÷ 100

y = 1.5

$14.25 + $1.50

$15.75

charle [14.2K]

Answer:

3.6miles

Step-by-step explanation:

Given:

distance of tent from the closest point on shore-line, d=3miles.

distance between shoreline point and coral reef, x=2miles

The shortest distance (say l) that the visitor runs towards the reef in order to swim a minimum distance which takes least time.

\therefore l^2=d^2+x^2\\l=\sqrt{3^2+3^2} \\l=3.6\ miles

Now on reaching at the shore at this point the visitor will have to swim the least distance due east to reach coral reef.
