A square field has an area of 1000 m2. Laura wants to walk from one corner of the field to the opposite corner. If she walks at 1.5 m/s, how much time can she save by walking diagonally instead of walking along two adjacent sides? Express your answer to the nearest tenth of a second.

First you would find what the side length of the square is:

Now that you know its 63.24 s walking along the two sides you need to find the diagonal way.

Now you subtract both of them so you can find the difference. Then you have to divide 18.53 by 1.5

which is

12.353 because you know Laura walks 1.5 m/s.

The answer is:

If Laura walks diagonally instead of walking the two whole sides, she saves 12.3 s
