a car travelled the half of the road at a speed of 60 miles per hour, 1/3 part of the road it travelled at a speed of 60 miles per hour and the rest of the road it travelled at a speed of 100 miles per hour. what was the average speed (in miles per hour) of the car on the entire road?

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%

31/6= 19/6 19/6 *1/7=19/42
