$2.25

Step-by-step explanation:

If Emmanuel was charged $32 for a taxi ride.

We are to determine how much Emmanuel was charged for each kilometer of the taxi ride.

If a taxi ride costs $32.

Then: 1 km will cost  $

Let us simplify the division.

Next we change the division sign to multiplication by taking the inverse of

From our calculations, 1 km taxi ride will cost Emmanuel $2.25.

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
