​

he left home at 10 am

he rested two times

he travled 80 km

he travled 160 km total

he returned home at 9 pm

he was traveling at 26.67 km/hr while returning home

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

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
