Question

In order to cover a certain distance in a shorter time span, the object should have a greater _________.

• A. mass
• B. speed
• C. time period
• D. frequency

Answer 1

The correct option is B

speed

We know that:
$Speed=\frac{Distance}{Time}$
Here, the object has to cover a certain fixed distance in a shorter span of time.
From the equation above, we understand that greater the speed, lesser is the time taken, provided the distance is constant.
So, in order to cover a certain distance in a shorter time span, the object should have a greater speed.
