Find Velocity Given Distance

Introduction to find velocity given distance:

The average speed or Velocity of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero . (Source-Wikipedia)
If the distance(d) and the time taken(t) is given, the speed can be calculated using the following formula:
Velocity(V) = Distance / Time taken

In this article to find velocity given distance, we are going to see some of the problems involved in finding the velocity if the distance is given.

Examples for finding velocity:


The Example problems for finding velocity if the distance is given are as follows:

1) Find the Velocity of an object which travels 275 metres in 20 seconds.

Solution:

Given:     Distance = 275 m

Time  = 20 sec

Velocity  = Distance / Time taken

= 275 / 20

= 13.75 m/sec

2) Find the Velocity of an object which travels 340 metres in 10 seconds.

Solution:

Given:     Distance = 340 m

Time  = 10 sec

Velocity  = Distance / Time taken

= 340 / 10

= 34 m/sec

3) Find the Velocity of an object which travels 467 metres in 45 seconds.

Solution:

Given:     Distance = 467 m

Time  = 45 sec

Velocity  = Distance / Time taken

= 467 / 45

= 10.38 m/sec

4) Find the Velocity of an object which travels 325 metres in 32 seconds.

Solution:

Given:     Distance = 325 m

Time  = 32 sec

Velocity  = Distance / Time taken

= 325 / 32

= 10.16 m/sec

I have recently faced lot of problem while learning percentage change calculation formula, But thank to online resources of math which helped me to learn myself easily on net.

Practice problems to find velocity given distance:


1) Find the Velocity of an object which travels 345 metres in 11 seconds.

Answer: 31.36 m/s

2) Find the Velocity of an object which travels 271 metres in 20 seconds.

Answer: 13.55 m/s

3) Find the Velocity of an object which travels 200 metres in 5 seconds.

Answer: 40 m/s

4) Find the Velocity of an object which travels 115 metres in 5 seconds.

Answer: 23 m/s
