The Distance at Speed calculator computes the distance travelled over time at a constant speed..
INSTRUCTIONS: Choose units and enter the following;
- (S) Speed
- (t) Time (duration) at Speed
Distance at Speed (D): The calculator returns the distance in miles. However, this can be automatically converted to other length or distance units via the pull-down menu.
The Math / Science
The formula for distance traveled at a constant speed is:
D = s * t
where:
- D = Distance Traveled
- s = speed (velocity)
- t = duration of travel

Forensic Science Calculators
- Time to Overtake: Computes the time for one object to overtake another.
- Distance to Overtake: Computes distance traveled to overtake another.
- Speed to Overtake by Distance: Computes the average velocity to overtake another within a specified distance.
- Speed to Overtake by Time: Computes the speed needed to overtake within a specified time.
- Distance at Speed: Computes the distance traveled over a period of time at a constant velocity (speed)..
- Braking Distance: Computes the distance to stop a vehicle based on the initial velocity (vi) and the a braking coefficient (μ).
- Total Stopping Distance: Computes the distance to stop a vehicle based on the initial velocity (vi), reaction time (t) and the a braking coefficient (μ).
- Speed from the Braking Distance: Estimates the initial speed based on the distance to stop a vehicle (d) and the a braking coefficient (μ).
- Speed from Length of Skid Marks: Estimates the speed based on the length of skid marks and the friction coefficient.
- Minium Drive Time between Coordinates: Computest the minimum time it would take to drive between two GPS coordinates in a straight line at a specified speed.
- Time of Death: Computes the amount of time since a human has died based on the current body temperature and the ambient temperature of the air around the body.
- Time to Sink: Estimates the time it takes for the inflow of water to surpass the vessel's displacement based on the vessel's displacement and the flow rate of sea water entering the hull and the bilge pump rate out.
