An ant is 1.2 cm up a wall and climbs up 1.7 cm each second. A
second ant is 30 cm up the wall
and climbs down 1.5 cm each
second. After how many seconds
will the ants be the same height
up the wall ?

step-by-step :

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
