Atrain travels a total distance of 470 miles in 10 hours. during the first part of the trip, the average speed of the train was 55 miles per hour. during the second part of the trip, the average speed was 45 miles per hour. how many hours did each part of the trip take?

anser is a

step-by-step explanation:

negitive slope

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
