To find how many miles per hour each bird is flying you would take the total miles and divide them by the hours it took them to fly. For the hummingbird you would take 210 miles and divide it by 7, so 210/7 = 30mph. For the goose you would take 165 miles and divide it by 3, so 165/3 = 55mph. The humming bird can fly 30 miles in an hour and the goose can fly 55 miles in an hour, therefore the goose flies at a faster rate.
The answer is Infinitely because if the sides are parallel then the other two sides must be the same measurement. However, they can be any measurement they want. So the answer is infinite triangles.
