Answer:

D. $2\frac{4}{7}\text{ mph}$

Step by step explanation:

First of all we will convert our given time from minutes to hour by dividing 35 by 60.

$35 \text{ minutes}=\frac{35}{60} \text{ hours}$

Let us find speed of dog during walk.

$\text{Speed of dog}=1.5 \div \frac{35}{60}$

Dividing a number by a fraction is same as multiplying the number by the reciprocal of the fraction.

$\text{Speed of dog}=1.5\times \frac{60}{35}$

$\text{Speed of dog}=\frac{1.5\times 60}{35}$

$\text{Speed of dog}=\frac{90}{35}$

$\text{Speed of dog}=\frac{18}{7}$

$\text{Speed of dog}=2\frac{4}{7}$

Therefore, speed of dog is $2\frac{4}{7}\text{ mph}$ and option D is the correct choice.
