Alright, let's see how we can use the formula you've mentioned: distance = velocity x time.
The formula implies that the total distance traveled by a body is the product of its velocity and the time taken.
Firstly, we need to know the velocity of the body. Velocity is the measure of the speed of a body in a specific direction. It could be in kilometers per hour, miles per hour, meters per second, depending on the unit you are using.
Secondly, we must know the time for which the body has been moving at that velocity. The time could be in seconds, minutes, hours, again depending on your velocity unit.
The final step is applying these values in the formula. You multiply the velocity by the time. The resultant value will be the distance covered by the body. This distance will be in the same unit as the velocity unit per the time unit. For example, if the velocity was in kilometers per hour and time was in hours, the distance will be in kilometers.
That's how you can calculate the distance from the velocity and time taken.
