# Speed Distance Time

Speed distance time gives the information about speed distance time formula and related problem of speed distance time problem with solution of class 5, Speed formula, Distance formula, Time Formula, Average Speed, Relative speed.

## Introduction

### Speed Formula

It is defined as the distance covered by a unit time. It is the rate at which the distance is covered and Uint of Speed is commonly taken as km/h.

Speed = Distance/Time

• To Convert speed km/h to m/s multiply speed by 5/18.
• Convert m/s to km/h multiply speed by 18/5.

### Time Formula

Time = Distance / Speed

It is defined as a quantity, which governs the order of sequence of an occurrence. In the absence of time is actually sequence of any occurrence or indecent would be lost. If we did not have the concept of time. We would not be able know what period or in what order something took place and Unit of Time Hour (h) and second (s) are mostly in taken are unit of time.

### Distance Formula

Distance = Speed*Time

When an object is moving one place to another in certain path then the path covered by the object is called the distance and Unit of Distance is kilo mete (km) and meter (m) are mostly used in distance.

Different Type Of Speed

#### Average Speed

It means total distance covered by the total time and formula of average speed.
Average speed = (Total distance covers)/ (Total Time)

#### Relative Speed

Relative speed means when two bodies are moves together in same direction or opposite direction then the bodies are relative to each other.

• Lets two body A and B.
• If A and B are going opposite to each other then the relative speed is A+B.
• A and B are  in same direction in different speed then the relative speed is A-B.
• Two object A and B are going in same direction at same speed then the relative speed is zero.
