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.
Answer:

Step-by-step explanation:
length of side x will be
Tan tita = opp/adjacent
tan65 = x/3
tan 65 is 2.14
so...you are left with 2.14=x/3
by cross multiplying
x= 2.14 × 3
= 6.43
