Question

Time required to travel a certain distance depends on ______ of the object.

• A. mass
• B. speed
• C. weight
• D. dimension

Answer 1

The correct option is B speed

Speed is defined as $speed=\frac{distance}{time}$
In terms of time taken, the above expression can be re-written as:
$time=\frac{distance}{speed}$
The distance covered is certain(constant) here. This implies, the time taken by an object to cover this distance depends on the speed of the object.
