 In this article, we will discuss the speed formulas and time and distance aptitude questions. As this topic forms an integral part of every competitive exam, you cannot afford to miss this topic. This article will equip you to solve all time, speed and distance word problems MCq

Average Speed Formula

Average speed = Total Distance covered/ Total Time Taken
When the distance is constant: Average speed = 2xy/x+y; Where, x and y are the two speeds at which the same distance has been covered.
When time taken is constant: Average speed = (x + y)/2; Where, x and y are the two speeds at which we traveled for the same time.

Time and Distance Formula

Distance = Speed × Time. Using this formula, all basic problems can be handled. However, you need to make sure about the correct usage of units while using the above formulas.
Speed is inversely proportional to the time taken when distance travelled is constant. So when speed increases, time decreases and vice versa.

Relative Speed

Relative speed is defined as the speed of a moving object with respect to another. When two objects are moving in the same direction, relative speed is calculated as their difference. When the two objects are moving in opposite directions, relative speed is computed by adding the two speeds.
