Question

Which describes a value for density?

a value for volume, such as m3, divided by a value for mass, such as kg
a value for mass, such as kg, divided by a value for volume, such as m3
a value for distance, such as m, divided by a value for time, such as s
a value for time, such as s, divided by a value for distance, such as m

Answer 1

Second option: a value for mass (kg) divided by a value for volume (m³). That's density (units kg/m³). The first option is the inverse (specific volume); the third is speed (m/s); the fourth is pace (s/m).
