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?
A) 2d = 570
B) d + 255 = 570
C) d - 255 = 570
D) d - 570 = 255
Give me the correct answer to the question.
B) d + 255 = 570
The equation that could be used to solve this problem is B) d + 255 = 570.
To solve this problem, we need to determine how far David traveled when Mark traveled 255 miles.
Let's look at the equation options:
A) 2d = 570
B) d + 255 = 570
C) d - 255 = 570
D) d - 570 = 255
Option A, the equation 2d = 570, does not represent the scenario given in the problem. It suggests that twice the distance David traveled equals 570 miles, but there is no information about David's distance or any indication of doubling.
Option B, the equation d + 255 = 570, correctly represents the scenario. Here, we know that Mark traveled 255 miles, and we need to find the distance David traveled. By adding 255 to the unknown distance David traveled (d), we should get the total distance traveled by both (570 miles).
Option C, the equation d - 255 = 570, does not represent the actual scenario given. Subtracting Mark's distance traveled from David's would not give us the total distance of 570 miles.
Option D, the equation d - 570 = 255, does not represent the scenario either. Subtracting the total distance from David's distance does not make sense in this context.
The correct answer is B) d + 255 = 570.
