4
1
4
miles per hour.

Answer 1

3 miles per hour

Explanation:

Answer 2

For this case we have the dog ran
`\frac {3} {4}`mile in
`\frac {1} {4}` of an hour.

Then, we must find the unit rate, for this we divide:

`\frac { \frac {3} {4}} {\frac {1} {4}} = \frac {4 * 3} {4 * 1} = \frac {12} {4} = 3`

Thus, the rate is
`3 \frac {miles} {hour}`

Mark's dog runs at a rate of
`3 \frac {miles} {hour}`

ANswer:

`3 \frac {miles} {hour}`
