Amap has a scale of 3.5 inches = 20kilometers. if the distance between two cities on the map is 4.9 inches, what is the actual distance between the two cities?

Hey. let me you on this one.in order for us to solve this problem, we will be needing to set up a ratio of inches to kilometers, and then, using that ratio, find the length of 4.9 inches in actual kilometers.  make sure to check out the image i will be attaching as well. it will include all the steps alongside the instructions. it should you on your studies.so, let's form a ratio of 3.5 inches over 20 kilometers, and then, compare it to the ratio of 4.9 inches over the unknown amount of kilometers.now, let's divide 20 by 3.5 so we can then form an equation with 4.9.awesome! now, we can form an equation with 4.9 in it. we will simply do the same expression like in the step above, but with numerator changed.now, let's get rid of 4.9 on both sides. it can be done by multiplying 4.9 on both sides.done! we have solved the equation. if you want, you can round it to 28 kilometers. there is only 0.002 difference.  answer: 27.998 miles is 4.9 inches on the map, which can be rounded to 28 miles.
