Answer

(a) 228 miles (b) 57 miles

Work Step by Step

(a) To find the number of miles traveled, we multiply the fraction $4/5$ by the total trip length ($285$ miles): $\frac{4}{5}*285=\frac{4*285}{5}=\frac{4*57}{1}=228$ miles (b) To find the number of miles that remain, we subtract the miles travelled from the total trip length: $285-228=57$ miles
