Question

Mr. West is standing on a cliff that is 25 1/5meters above the surface of the ocean. He spots a dolphin that is 2 3/5 meters under the water. What was the total distance from Mr. West to the dolphin?

Answer 1

Total distance from Mr. West to dolphin
`=27(4)/(5)\ meters`

Explanation:

Height of cliff on which Mr. West is standing above the surface of ocean =
`25 (1)/(5) \ meters`

Mr. West spot the dolphin under the water at a depth of =
`2(3)/(5) \ meters`

∴ Total distance from Mr. West to dolphin=
`(25 (1)/(5)+2(3)/(5))\ meters`

Adding mixed numbers

`(25 (1)/(5)+2(3)/(5))`

Adding whole numbers first.

`=25+2+(1)/(5)+(3)/(5)\\=27+(1)/(5)+(3)/(5)`

Adding fractions by taking LCD.

`=27+(1+3)/(5)\\=27+(4)/(5)\\=27(4)/(5)\ meters`
