Question

I had been trying but yhe thing that i  really dont get is if i have to múltiple add divide or subtract

Answer 1

If you are unsure of what to do in a situation like this, draw a picture.  Draw a track, a rectangle with the length labeled 50 yd.  I draw a stick figure person then show using arrows them running the six lengths.  You can add all of those lengths together or you can use multiplication since the lengths are all equal.  6 * 50 yd = 300 yd.
