To find Sarah's walking pace in miles per hour, divide the distance she walks by the time it takes her.

Walking pace (in miles per hour) = Distance / Time

First, convert the time from minutes to hours: 50 minutes is ( \frac{50}{60} = \frac{5}{6} ) hours.

Then, divide the distance by the time:

( \text{Walking pace} = \frac{1 \frac{3}{4}}{\frac{5}{6}} )

( \text{Walking pace} = \frac{\frac{7}{4}}{\frac{5}{6}} )

Multiply the numerator by the reciprocal of the denominator:

( \text{Walking pace} = \frac{7}{4} \times \frac{6}{5} )

( \text{Walking pace} = \frac{42}{20} )

( \text{Walking pace} = 2.1 )

So, Sarah's walking pace is 2.1 miles per hour.
