The answer is A (360/53=6.8)
Answer:
10 feet
Step-by-step explanation:
Let the length and the age of the sea turtle be L inches and A years old respectively.
Since its length is directly proportional to its age,
L= kA, where k is an unknown constant.
Let's find the value of the constant k.
L= kA
When L= 3, A= 2,
3= k(2)
2k= 3
k= 3 ÷2
Substitute the value of k back into the equation:
When A= 80,
L= 120
Length of sea turtle
= 120 inches
= (120 ÷12) feet
= 10 feet
Answer:
700 miles per hour
Step-by-step explanation:
In miles per hour, the jet traveled 350/0.5 (30 minutes is half of an hour)
So the plane traveled (2*350)/(2*0.5) = 700/1
700 miles per 1 hour
