It will take Wanda and Miranda 0.375 hours to be 9 miles apart

Wanda's speed = 6 miles per hour

Miranda's speed = 30 miles per hour

Distance = Speed x time

Find the distance covered by Wanda in t hours

D_{wanda} = 6t

Find the distance covered by Miranda in t hours

D_{miranda} = 30t

Difference in the distances covered

D_{miranda} - D_{wanda} = 30t-6t\\\\D_{miranda} - D_{wanda} = 24t

The difference in their distance is 9 miles

9 = 24t

To find the time, divide both sides by 9

\frac{9}{24} = \frac{24}{24}t\\\\t =   \frac{9}{24}\\\\t = 0.375

It will take Wanda and Miranda 0.375 hours to be 9 miles apart
