Please give an explanation. Don't just give straight up answers.

Let me explain. You need to multiply 40 x 3 to get the answer 120. then you multiply 120 by 2 which equals 240. :) so now we need to know how we got that answer. We got that answer by using the amount of miles she walked on each day together so the correct answer is B. Do you understand? :)

Oh and the reason we no its in miles is because they asked how FAR she walked
