Question

Dora can run 3/5 mi in 3/20 h.

How far can she run in 1 h?

mi

Answer 1

so do we use the same form

Answer 2

\frac{\frac{3}{5} \ mi}{\frac{3}{20} \ h}=\frac{3}{5} \times \frac{20}{3} \ \frac{mi}{h}= \frac{20}{5} \ \frac{mi}{h}=4 \ \frac{mi}{h} = \frac{4 \ mi}{1 \ h}

In 1 h she can run 4 miles.
