Answer:
option 2
Step-by-step explanation:
consider the coordinates A (- 3, 4 ) and A' (- 1,
)
since the dilatation is centred at the origin, then corresponding coordinates are multiples/ divisors of each other, then image to original gives scale factor.
scale factor =
=
=
and
= 
similarly B (1, - 2 ) and B' (
, -
)
=
and
= 
The correct answer is
d=50t
Where; d is the distance covered in miles
t is the time taken in hours
The two is in the tenths place.
