The concepts of speed, distance, and time are all intertwined. It is critical to comprehend the shared relationship between these three phenomena to correctly use the formulas in various sums. When the other two elements are known, several formulas can be used to determine any one of them.
Even though the notions of speed, time, and distance remain the same, the types of questions asked in tests may differ. Speed, time, and distance are three of the most prevalent quantitative aptitude themes addressed in government tests. Therefore, students must understand the importance of speed, time, and distance.
What Is Speed?
The rate at which a body moves from one location to another is referred to as speed. A body’s speed is the distance it travels in a given amount of time. The movement of an object in any given direction is referred to as distance. With the help of the other two terms, the value of speed may be calculated.
Types of Speed
There are three main types of speeds. Let’s look at each of them with examples.
- Uniform Speed: An object is considered to be in uniform speed when it is travelling the same distance in the same amount of time.
For example, if an automobile travels 60 kilometres in the first hour, 60 kilometres in the second hour, and 60 kilometres in the third hour, the car is said to be travelling at a uniform pace of 60 kilometres per hour.
- Variable Speed: An object is considered to be travelling with variable speed if it travels a varying distance in the same period.
For example, if an automobile drives 45 kilometres in the first hour, 54 kilometres in the second hour, and 65 kilometres in the third hour, the car has a variable speed.
- Average Speed: If a moving object travels different distances d1, d2, d3, …. dn with different speeds V1, V2, ……, Vn m/sec in time t1, t2, …., tn seconds,
Total Distance Travelled/Total Time Taken = Average Body Speed
= d1+d2+d3…..dn/t1+t2+….tn
Relation between Time, Speed, and Distance
Let’s find the answer to “How are speed, time, and distance related?”
Speed is equal to Distance/Time.
Distance is equal to Speed*Time.
Time is equal to Distance/Speed
Time
The time formula determines how long it takes an object to traverse a given distance at a particular speed.
The SI unit of time is measured in seconds (s).
Distance
The distance between two places is the length of the line segment that links them. The distance is the amount of space between two objects, such as points or lines.
The SI unit for distance is metre.
Relation of Speed, Time, and Distance
Now, we’ll look at how speed, distance, and time are related mathematically. A moving body’s speed is the distance it goes in a given length of time.
Speed = Distance/Time
The speed is measured in kilometres per hour while the distance is measured in kilometres and the time is measured in hours.
If the distance is measured in metres and the time is recorded in seconds, the speed is m/sec.
Distance is equal to speed*time.
Metre is the SI unit for distance.
Time is equal to distance/speed.
Seconds is the SI unit for time (s).
