Question

A Pacific salmon can swim at a maximum speed of 8 mi/h. The function `y =8x` describes how many miles `y` the fish swims in `x` hours. What is the number of miles the fish swims in 3.5 hours?

Answer 1

`28` miles

Explanation:

If the time is `3.5`, `x=3.5`,

`y=8(3.5)`
`color(white)(y)=28`

If `y=28`, the number of miles the fish swims is `28` mi.
