If 60 gal of oil flow through a certain pipe in 16 minutes, how long will it take to fill a 45 gal tank using this pipe?

solve for x which is the amount of time it takes to fill the 45 gallon tank.

Step-by-step explanation:

set 60/16 equal to 45/x and cross multiply. use your algebra steps

the answer is 489

step-by-step explanation:

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
