A motorcyclist took 40 minutes to travel 50 km. The distance travelled by the motorcyclist is 6 km more than the distance a bus driver would cover in 45 minutes. Find the difference between the average speed of the motorcyclist and that of the bus driver.

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
