Answer:
A & E
Step-by-step explanation:
[tex]2\frac{1}{2} mph = \frac{5}{2} mph \\\\A. \frac{\frac{3}{4} }{\frac{3}{10} } = \frac{30}{12} = \frac{5}{2}\ YES \\\\B. \frac{\frac{3}{2} }{\frac{3}{4} } = \frac{12}{6} = 2\ NO \\\\C. \frac{\frac{3}{5} }{\frac{3}{2} } = \frac{6}{15} = \frac{2}{5}\ NO \\\\D. \frac{\frac{2}{1} }{\frac{5}{6} } = \frac{12}{5} \ NO \\\\E. \frac{\frac{5}{6} }{\frac{1}{3} } = \frac{15}{6} = \frac{5}{2}\ YES \\[/tex]
