Answer:
The Juan's distance from home is 2964 miles.
Explanation:
Given that,
Distance = 77 miles
Let Juan's distance from home be x miles
.
Now, the distance between Juan and Mary = 1+x
Now since Mary heads north and Juan east
Using Pythagorean theorem
[tex]77^2+x^2=(1+x)^2[/tex]
[tex]5929+x^2=1+x^2+2x[/tex]
[tex]2x=5929-1[/tex]
[tex]x=\dfrac{5928}{2}[/tex]
[tex]x=2964\ miles[/tex]
Hence, The Juan's distance from home is 2964 miles.
