Question

Which of these is an example of inverse proportion?

• A. Speed and time when distance is constant
• B. Number of apples bought to the money spent on the same
• C. Distance and time when speed is constant
• D. Cake produced to the amount of maida used

Answer 1

The correct option is A

Speed and time when distance is constant

When speed increases we take less time to travel the same distance. Hence, speed and time are inversely proportional when distance is constant.

Other options are examples of direct proportion.
