Question

Choose the equation that could be used to solve this problem.

Together, Mark and David traveled 570 miles to the beach. If Mark traveled 255 miles, how far did David travel

Answer 1

To determine how far David traveled, we can set up the equation based on the total distance traveled by both Mark and David.

Let \( d \) represent the distance David traveled. The relationship can be described by the following equation:

\[
255 + d = 570
\]

This equation indicates that the distance Mark traveled (255 miles) plus the distance David traveled (\( d \)) equals the total distance (570 miles).

To solve for \( d \), you would subtract 255 from both sides:

\[
d = 570 - 255
\]

Thus, the equation you can use to solve the problem is \( 255 + d = 570 \).
