Question

it takes Sarah 50 minutes to walk to her friend's house 1 3/4 miles away. What is her walking pace in miles per hour?

Answer 1

50 min = 5/6 hours


1 3/4 miles = 7/4 miles


$\frac{\frac{7}{4} }{\frac{5}{6} }$ = $\frac{7}{4} * \frac{6}{5} = \frac{42}{20} = \frac{21}{10} = 2.1$

Therefore, the walking rate is 2.1 miles per hour
