Answer:
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.
