If sally walked 1⁄2 kilometer in 1⁄4 hour, how fast, in kilometers per hour, was she walking?

Sally walks at a speed of 2 kilometers per hour.

Step-by-step explanation:

Given data

We can find the speed (v) of Sally using the following expression

v = d/t = (1/2 km) / (1/4 h) = 2 km/h

Sally walks at a speed of 2 kilometers per hour.

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.
