An​ alligator's tail length is proportional to its body length.

Question

An alligator's tail length is proportional to its body length. An alligator with a body length of
6.3 feet has a tail length of
7.1 feet. What is the tail length of an alligator whose body length is
9.4 feet?

Answer 1

Settig up the proportion of 6.3/7.1= 9.4/x yields x=10.59 ft.

Answer 2

Let T1 = tail length of first alligator = 7.1 ft

     B1 = body length of first alligator = 6.3 Ft

     B2 = body length of second alligator = 9.4 ft 

 

T1/B1  = (7.1/6.3) =  constant

 

T2/B2 = constant

 

T2 = B2*constant = 9.4*(7.1/6.3) = 10.6 ft tail length of second alligator
