QuestionB) In a relay race Joan ran $2 / 5$ of a mi, Mark ran $2 / 3$ of a mi, and Ida ran $1 / 2 \mathrm{mi}$. How long was the race?

Studdy Solution
Simplify the fraction if necessary. In this case, $\frac{47}{30}$ is already in its simplest form.
The total length of the race is:
$\boxed{\frac{47}{30} \text{ miles}}$
