Answer:
Total distance from Mr. West to dolphin [tex]=27\frac{4}{5}\ meters[/tex]
Step-by-step explanation:
Height of cliff on which Mr. West is standing above the surface of ocean =[tex]25 \frac{1}{5} \ meters[/tex]
Mr. West spot the dolphin under the water at a depth of = [tex]2\frac{3}{5} \ meters[/tex]
∴ Total distance from Mr. West to dolphin=[tex](25 \frac{1}{5}+2\frac{3}{5})\ meters[/tex]
Adding mixed numbers
[tex](25 \frac{1}{5}+2\frac{3}{5})[/tex]
Adding whole numbers first.
[tex]=25+2+\frac{1}{5}+\frac{3}{5}\\=27+\frac{1}{5}+\frac{3}{5}[/tex]
Adding fractions by taking LCD.
[tex]=27+\frac{1+3}{5}\\=27+\frac{4}{5}\\=27\frac{4}{5}\ meters[/tex]
