$Answer: \text{Sloth covers }9\frac{3}{8}\text{in 90 minutes.}$

Explanation :

Since we have given that

$\text{in 1 hour sloth may move = }\frac{250}{5\times 8}$

$\text{ In 60 minutes , sloth may move = }\frac{25}{4}$

$\text{ In 1 minute, it may move = }\frac{25}{4\times 60}\\\\\text{ In 1 minute, it may move = }\frac{5}{48}$

$\text{ In 90 minutes, it may move}\\=\frac{5\times 90}{48}\\ \\=\frac{75}{8}\\\\=9\frac{3}{8}$

∴ $\text{Sloth covers }9\frac{3}{8}\text{in 90 minutes.}$
