Answer:

temperature on the beach = T2 = 34.56 °C

Step-by-step explanation:

We are given;

P1 = 4.5 atm

T1 = 24 °C = 24 + 273 = 297 K

P2 = 4.66 atm

Thus, P1/T1 = P2 /T2

So, T2 = P2•T1/P1

Thus, T2 = (4.66x 297)/4.5

T2 = 307.56 K

Let's convert to °C to obtain ;

T2 = 307.56 - 273

T2 = 34.56 °C

Answer:

19.209 miles from each other.

Step-by-step explanation:

Using this we get:

${15}^{2} + {12}^{2} = {x}^{2}$

$225 + 144 = 369 = {x}^{2}$

$\sqrt{369 } = 19.209$
