Question:

The distance covered by a train in (x+1) hours is (x²-1) km. What is the speed of the train?

Options:

(x-1) km/h

(x+1) km/h

(x²-1) km/h

(x+2) km/h

Correct Answer:

(x-1) km/h

Explanation:

Distance = Speed × Time

(x² - 1) = S × (x + 1)

⇒ S = $\frac{(x - 1) (x + 1)}{(x + 1)}$

⇒ S = (x - 1)
