Speed

A Speed value represents a speed in meters per second, miles per hour etc. It is stored as a number of meters per second.

Note that since MetersPerSecond is defined as Rate Meters Seconds (length per unit time), you can construct a Speed value using Quantity.per:

speed =
    length |> Quantity.per duration

You can also do rate-related calculations with Speed values to compute Length or Duration:

length =
    speed |> Quantity.for duration


alsoLength =
    duration |> Quantity.at speed


duration =
    length |> Quantity.at_ speed
