Question

Bill caught three catfish and one trout. Two of the catfish were 19 in long. The other was 16.9 in long and the trout was 17.2 in long. What was the average length of the catfish? A. 16.2 in B. 17.6 in C. 18.3 in D. Not given

Answer 1

C. 18.3 in

Step-by-step explanation:

Forget the trouts, since we are only asked about the length of the catfish.

Now bill caught three catsfish. Let us see their lengths.

Length of catfish 1 = 19 in

Length of catfish 2 = 19 in

Length of catfish 3 = 16.9 in

Therefore, the average length of the three catfish is

`(19+19+16.9)/(3)=18.3`

Hence, the average length of the catfish is 18.3 in. Therefore, choice C is the correct answer!
