# Distance Speed Time Formula

Speed is a very basic concept in motion which is all about how fast or slow any object moves. We define speed as distance divided by time. Distance is directly proportional to Velocity when time is constant. Speed, distance, and time problems ask us to solve for one of the three variables given certain information. In these problems, we deal with objects moving at either constant speeds or average speeds.

Speed Distance Time Formula
is mathematically given as:

Where
x is the Speed in m/s,
d is the Distance traveled in m,
t is the time taken in s.

Distance traveled formula is given by

If any of the two quantities among speed, distance and time is given, we can use this formula and find the unknown quantity.

## Speed Distance Time Formula Problems

Below are solved problems based on speed distance and time formula:

### Solved Examples

Question 1: Lilly is driving a scooty with the speed of 6 km/hr for 2hr. How much distance will she travel?
Solution:

Given: Speed of the scooty x = 6km/hr
Time taken t = 2 hr
Distance traveled d = ?
Speed distance time formula is given as: x = $\frac{d}{t}$
Distance traveled d = x $\times$ t
= 6 km/hr $\times$ 2 hr
= 12 km.

Question 2: A man rides the bike with the speed of 60 miles in $\frac{3}{4}$th hours. Calculate the speed of the bike?
Solution:

Given : Distance Covered d = 60 miles,
Time taken t = $\frac{3}{4}$ hours.
Speed is calculated using the formula: x = $\frac{d}{t}$
= $\frac{60 miles}{\frac{3}{4} hr}$
= 60 miles $\times$ $\frac{4}{3 hr}$
= 80 miles/hr.

Question 3: A cycle race is going on, a cyclist is moving with the speed of 2 km/hr. He has to cover a distance of 5 km. How much time will he need to reach his destiny?
Solution:

Given: Speed x = 2 km/hr,
Distance Covered d = 5 km,
time taken t = ?
Speed is given by formula: x = $\frac{d}{t}$
Time taken t = $\frac{d}{x}$
= $\frac{5 km}{2 km/hr}$
= 2.5 hr
= 9000 s.
Time taken by the Cyclist is 2.5 hr.
