Guide: Speed, Distance, Time
What it does
Rearranges v = d/t to find the missing variable.
How to use it
Enter any two of distance, speed, time; leave the third empty.
Formula
v = d/t; d = v×t; t = d/v.
Example
120 km in 2 h → 60 km/h.
FAQs
Do units need to match?
Yes—use consistent pairs (miles with hours, km with hours).
Average vs instantaneous speed?
This model assumes constant speed over the interval.
Metric vs imperial?
Convert to one system before entering; don’t mix miles with km without converting.
