A track star ran the 100-meter event in six track meets. Her average time for all six meets was 11.8 seconds. She could not find the record for her running time in the last meet, but she had all the other ones: 11.1 seconds, 11.2 seconds, 12 seconds, 12.1 seconds, 11.7 seconds. What was her running time for her last meet?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
