Asailboat is traveling at a speed of 10 nautical miles per hour if one nautical mile is 6076 feet what is the speed of the sailboat in feet per second

16.88 feet per second

Step-by-step explanation:

We are given;

We are required to convert the speed into ft per second.

Therefore;

10 nm = (10 nm × 6076 ft/nm)

           = 60760 ft

1 hour = 3600 secs

Therefore;

Speed in ft per sec = 60760 ft ÷ 3600 secs

                                = 16.88 ft per second

Thus, the speed of the sailboat is 16.88 feet per second

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
