Question

The average length of a king cobra is 118 inches, which is 22 inches longer than a black mamba. Write and solve an equation to find the average length of a black mamba.

Answer 1

Let x=length of king cobra
Let y=length of black mamba

x=118
y=x-22
y=118-22
y=96
Therefore black mamba has an average length of 96 inches
