Distance is generally calculated in problems relating to the motion of an object. In case the motion is linear, that is if an object is moving in a straight line, there are two formula for measuring the distance.

First is when the motion is uniform. In this case Distance is calculated as d = time x velocity(or speed)

However, when motion is not uniform, its velocity, is varying constantly. In this case, the distance traveled is given by the formula s = ut + ½ at². Here u is the starting velocity, t is the time in which the distance traveled is required to be calculated and a is the acceleration. Acceleration means the rate at which the velocity of the object is changing per unit of time, which can be positive or negative depending upon whether the object is accelerating or slowing down.
