Step-by-step explanation

Since Brian drives at a constant speed, in order to get the rate, we need to compute the slope, by applying the slope equation, as shown as follows:


\text{Slope}=(y_2-y_1)/(x_2-x_1)

Where (x_1,y_1)=(20,100) (x_2,y_2)= (50,140)

Plugging in the terms into the slope equation:


\text{Slope}=(140-100)/(50-20)=(4)/(3)

In conclusion, the distance will increase by 4 miles per hour.
