what equation could be used to solve this problem

together mark and david traveld 570 miles to the beach. if mark traveled 255 mies how fa did david travel?

1 answer

Let's call the distance David traveled as x miles. We know that together, Mark and David traveled 570 miles. Thus, the equation that represents this information is:

x + 255 = 570

To solve for x, we can subtract 255 from both sides of the equation:

x = 570 - 255

Simplifying, we find:

x = 315

Therefore, David traveled 315 miles.
