We can write this as the ration 560(kilometers):1(hours). Using this ration you need to find what multiplied to 560 equals 140. To do this you can do 140 / 560 which would equate to 0.25. Multiplying 560 by 0.25 is 140 so if you multiply the other side of the ration by 0.25 then you would also get 0.25. The answer would be A. 0.25 hours
