## Calculating speed from distance and time

If an object travels a distance d for a duration t, then its average speed v is defined by: v = d / t

Speed, distance and time are therefore related by a formula.

The speed is then equal to the distance divided by the time.

Example:

By car, for example, we drive at 50 km / h, so we calculate the distance (kilometers) by time (hour).

## Calculating distance from speed and time

In some cases, it may be necessary to calculate the distance traveled during a given time at a given speed.

We must therefore isolate d in the formula, using the equality of the cross products and remembering that v = d / 1

We then obtain that d = v x t

The distance is therefore equal to the product of time times the speed

Example:

A car travels at 50 km / h, how far does it travel in 4 hours?

We can apply the formula:

d = v x t = 50 x 4 = 200 km

## Time calculation from speed and distance

We can also calculate the time by knowing the speed and the distance.

We then obtain t = d / v

Time equals distance divided by speed.

Example:

A car travels at 50 km / h, how long does it take to travel 75 km

We can apply the formula:

t = d / v = 75/50 = 1.5

Warning: 1.5 corresponds to decimal hours

1.5 = 1 hour and 30 minutes
