mixer [17]

Answer:

three eighths over three fifths = five eighths mile per hour which is the same as \frac{3}{8}/\frac{3}{5}=\frac{5}{8}miles per hour

Explanation:

You need to use the rule of three of maths.

1)  \frac{3}{8} miles in \frac{3}{5} hours

It´s the same as \frac{3}{8} miles----------------------\frac{3}{5} hours in maths terms.

2) I need to know how much she wuold have walked in 1hour to calculate miles per hour. I apply the rule of three:

\frac{3}{8} miles----------------------\frac{3}{5} hours

X miles----------------------1hour

I can calculte X by solving: 1hour * \frac{3}{8} miles /\frac{3}{5} hours =\frac{5}{8}miles per hour which is the same as the first option

\frac{3}{8} miles /\frac{3}{5} hours =\frac{5}{8}miles

three eighths over three fifths = five eighths mile per hour
