alleryFor a fixed distance, if the speed is increased then the time taken:
ADecreases
BIncreases
CStays the same
DDoubles
Answer & Solution
Correct answer: A. Decreases
1. Speed and time are in inverse proportion when the distance is fixed.
2. If we increase the speed, the time taken to cover a given distance decreases.
3. Doubling the speed halves the time, and tripling it cuts the time to one third.
4. The product of speed and time stays equal to the distance throughout.
5. That constant product is what every question of this type turns on.
