A bus is running at a uniform speed. It covers a distance of 435 km in 6 hours. How much distance will it cover in 8 hours ?

Given:

Distance covered in 6 hours = 435 km

Distance covered in 8 hours = ?

Let distance covered in 8 hours = x km

Ratio of times : Ratio of distances

6 : 8 :: 435 : x

By the rule: Product of Extremes = Product of Means:

6 × x = 8 × 435

⇒ x = $\dfrac{8 \times 435}{6}$

⇒ x = 8 x 72.5

⇒ x = 580

Hence, the bus will cover 580 km in 8 hours.
