Question

An​ alligator's tail​ length, T, varies directly as its body​ length, B. An alligator with a body length of

3 feet has a tail length of 2.4 feet. What is the tail length of an alligator whose body length is

7 feet?

Answer 1

T = kB

2.4 = k*3

k = 2.4/3 = 24/30 = 4/5

T = (4/5)B

= (4/5)(7/1) = 28/5

5.6

Answer 2

Body B=3 and Tail T=2.4.B to T means B/T. A ratio is 3/2.4=7/T/ T=5.6
