Method: Joules.avg_speed

Defined in:
lib/joules/kinematics.rb

.avg_speed(distance, time) ⇒ Float

Calculates the average speed given distance and time.

Examples:

Joules.avg_speed(30, 2.4) #=> 12.5

Parameters:

  • distance (Int, Float) —

    distance >= 0; distance is in metres

  • time (Int, Float) —

    time > 0; time is in seconds

Returns:

  • (Float) —

    return value >= 0; return value is in metres per second

Raises:

  • (ZeroDivisionError) —

    if time = 0
