Juan is a lifeguard and spots a drowning child 50 meters along the shore and 40 meters from the shore to the child. Juan runs along the shore for a while and then jumps into the water and swims from there directly to the child. Juan can run at a rate of 4 meters per second and swim at a rate of 1.1 meters per second. How far along the shore should Juan run before jumping into the water in order to save the child? Round your answer to three decimal places.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.
