You start driving north for 48 miles, turn right, and drive east for another 64 miles. how many miles must you travel to return directly back to your starting point?

I have to travel 80 miles to return directly back to starting points

Step-by-step explanation:

Given as :

The distance travel by me as directed :

let the starting point = X

    The end point      = Y

I travel to north from point X , the distance cover = 48 miles ,

Now I turn to right , and travel to east and stop at Y , the distance cover = 64 miles

Let the distance travel from end point Y to starting point X = Z mile

So, From displacement method

        Z² =  X² + Y²

Or,    Z =

Or,    Z =

Or,    Z =

Or,    Z = 80 miles

Hence, I have to travel 80 miles to return directly back to starting points Answer
