How do i show work for this question? , a train travels at an average speed of 67.5 miles per hour. at this speed how far could the train travel in 3.25 hours

219.375 miles

Step-by-step explanation:

d = r * t

   = 67.5 * 3.25

   = 219.375

not sure but it may be b, as i said i'm not sure.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
