Answer:

K = 39.5

Step-by-step explanation:

We assume that when all the angles are added together they are equal to 360°, hence:

k + 3k + 87 + 115 = 360 \\  \\ 4k + 202 = 360 \\ 4k = 360 - 202 \\  4k = 158 \\

\frac{4k}{4} =  \frac{158}{4}  \\  \\  k = 39.5

Answer:

1 mile = 1,609 meters is the key to converting the rates of the two swimmers

Step-by-step explanation:

there are 60 seconds in a minute and 60 minutes in an hour

so 1.8 meters/sec x 60 sec/min x 60 min/hr = 6480 meters/hr

now we convert meters to miles

6480 meters/1 hr x 1 mile/1609 meters = roughly 4 miles/hr (4.027)

or we can convert the other rate to meters/sec

2.5 mi/hr x 1hr/60 min x 1min/60 sec = 0.00069444 mi/sec

then convert miles to meters

0.00069444 mi/sec x 1609meters/ 1mi = roughly 1.1 meters/sec (1.117)
