A train leaves East Glacier, Montana (elevation 4,560 feet) at 1:00 p. m. on a Sunday. The temperature is 80° F. The train
travels at a top speed of 70 miles per hour and gets to the next stop at 4:30 p. m. That stop is 189
miles away and its elevation is 9000 feet above sea level. What is the average speed of the train?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
