Rachel is trying to find the length of the lake shown on the diagram. she knows that if the two triangles are similar, she can use a proportion to solve for the length. how can rachel justify that the triangles are similar? what is the length of the lake?

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

answer:

c. the third graph

answer: 0.26
