A boy is running at a speed of p kmph to cover a distance of 1 km. But, due to the slippery ground, his speed is reduced by q kmph (p > q). If he takes r hours to cover the distance, then:
A. $$\frac{1}{r} = p - q$$
B. $$r = p - q$$
C. $$\frac{1}{r} = p + q$$
D. $$r = p + r$$
Answer: Option A
Solution (By Examveda Team)
$${\text{Speed }} = \frac{{{\text{Distance }}}}{{{\text{Time}}}}$$ or$$\frac{{{\text{Distance }}}}{{{\text{Time}}}} = {\text{Speed}}$$
⇒ $$\frac{1}{r} = p - q$$
