# Time Formula

The formula of time helps in calculating the time taken by an object to travel a certain distance at a given speed. The SI unit of time is** **s. Let us study the formula of time using some solved examples.

## What Is the Time Formula?

Time formula can be defined as the ratio of distance covered by an object to a unit speed. Time refers to the progression of events. This progression is in such a manner that it goes from the past to the present and finally into the future.

### Formula for Time

The Formula of Time of a given body can be expressed as,

**Time = Distance÷Speed**

## How To Use Time Formula?

Time formula can be used to find the time taken by an object, given the distance and unit speed. Let's take a quick look at an example showing how to use the formula for time.

**Example:** What will be the total time to cover 3600 m at 2 meter per seconds?

**Solution:** Using Formula for time,

Time = Distance ÷ Speed

Time = 3600 ÷ (2) = 1800 seconds.

**Answer: Total time taken to cover the distance of 3600 m is 1800 seconds.**

## Examples Using Time Formula

Let us solve some interesting problems using the time formula.

**Example 1: **A train covered a distance of 120 km at a speed of 60km/hr. Using the time formula calculate the time taken by the train in covering the distance.

**Solution: **

To find the time taken by the train.

Given:

Distance covered by a train = 120km

Speed of a train = 60 km/hr

Using** **Formula of Time,

Time = Distance/Speed

= 120/60

= 2 hr

**Answer: **The time taken by the train to cover 120 km at the speed of 60km/hr is 2 hours.

**Example 2: **A cyclist covers 20 km at a speed of 5km/hr. Use the time formula and find the time taken by the cyclist in covering the distance.

**Solution:**

To find the time taken by the cyclist.

Distance covered by a cyclist = 20 km

Speed of the cyclist = 5km/hr.

Using Formula of Time,

Time = Distance/Speed

= 20/5

= 4 hr

**Answer: **The time taken by the cyclist to cover 20 km at 5km/hr is 4 hours.

**Example 3: **Using the time formula calculate the time taken by a person in covering a distance of 400 kilometers at speed of 20 kilometers per hour?

**Solution: **

The formula for time is [Time = Distance ÷ Speed]

Distance = 400 kilometers

Speed = 20 km/hr

Time = (400 ÷ 20) hr

= 20 hours

**Answer: Thus the person covered a distance of 400 kilometers in 20 hours.**

## FAQs on Time Formula

### How To Calculate Distance Using Time Formula?

The formula for time is given as [Time = Distance ÷ Speed]. To calculate the distance, the time formula can be molded as [Distance = Speed × Time].

### How To Calculate Speed Using Time Formula?

The formula for time is given as [Time = Distance ÷ Speed]. To calculate the speed, the time formula will be molded as [Speed = Distance Travelled ÷ Time].

### How To Use the Formula for Time?

Time formula can be used in our day-to-day lives to find how much time is required in any task. To understand how to use the formula for time let us consider an example.

Example: In how much time will you be able to travel 4000m at a speed of 20m/s?

Solution: Using Formula for time,

Time = Distance ÷ Speed

Time = 4000 ÷ (20) = 200 seconds

Time required to finish the distance of 4000m at a speed of 20m/s is 200 seconds.

### What will Be the General Time Formula for any Task?

The general time formula for any task is given as [Time = Distance ÷ Speed]. SI unit of time is seconds (s).
