The distance a butterfly flies varies directly with it's time in the air. if a butterfly travels 264 ft in 0.5 min, how far will the butterfly travel in 1.25 min?

The butterfly travels 660 ft in 1.25 min.

Step-by-step explanation:

If the distance, d, a butterfly flies varies directly as the time,t in the air, then we can write the mathematical statement.

If we introduce the constant of proportionality, we obtain;

According to the question, when , .

We substitute these values to obtain;

The direct variation equation now becomes

When

Therefore the butterfly will travel 660 ft in 1.25 min.

the answer is  

a.

4,624π mm2
