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 "

$a^2+b^2=c^2\\\\4^2+3^2=c^2\\\\16+9=c^2\\\\25=c^2\\\\\sqrt{25}=c\\\\5\ miles=c$

Hence, His displacement will be 5 miles.
