Answer:
22.36 mile.
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, y is the distance between starting point and the end point.
Thus we can obtain the value of y by using the pythagoras theory as show below:
Note: y is the longest side other wise known as the Hypothenus.
y² = 10² + 20²
y² = 100 + 400
y² = 500
Take the square root of both side
y = √500
y = 22.36 mile
Therefore, the distance between the starting point and the end point is 22.36 mile
