Megan walked about 3 miles on Monday because if you divide 32,410 by 5 you receive 6,482 then, you would find out how many inches are in a mile which is 63,360 in one mile. After, you would multiply 6,482 by 63,360 and you would receive 410,699,520 but you would divide 410,699,520 by 63360 because there is that many inches in a mile and recieve 2.86 and other numbers so you round up and it is 3 miles sorry if I confuse you I can't explain well. But it is 3 miles
