Answer: His displacement will be 5 miles.
Step-by-step explanation:
Since we have given that
Distance traveled by William towards South = 3 miles
Distance traveled by William towards West = 4 miles
So, it will form "Right angled triangle "
So, we can apply "Pythagorus theorem "
[tex]a^2+b^2=c^2\\\\4^2+3^2=c^2\\\\16+9=c^2\\\\25=c^2\\\\\sqrt{25}=c\\\\5\ miles=c[/tex]
Hence, His displacement will be 5 miles.
