Question

The smith family walked 2/3 of a mile in 2/7 of an hour? What is their unit rate in miles per hour? Explain how this is determined. (Show complex fraction setup.)

Answer 1

Answer:
`2\frac13\text{ miles per hour}`

Explanation:

Given: Distance traveled by Smith =
`\frac23` mile.

Time taken =
`\frac27` hour

Unit rate in miles per hour = ( Distance traveled by Smith) ÷ (Time taken)

`=\frac23/\frac27`

`\\\\=\frac23*\frac72\\\\=\frac73\\\\=2\frac13\text{ miles per hour}`

Unit rate =
`2\frac13\text{ miles per hour}`
