Answer 1

Let M denote the distance Mark traveled and D denote the distance David traveled. The problem states that "Together, Mark and David traveled 570 miles to the beach" and "If Mark traveled 255 miles". Thus, we can set up the equation:

M + D = 570

Since we know that Mark traveled 255 miles, we can substitute M with 255 in the equation:

255 + D = 570

Therefore, the equation that could be used to solve this problem is 255 + D = 570.
