Task# Speed Conversions

Illustrative MathematicsVaries

The goal of this task is to perform a unit conversion in the context of speed while also focusing on the precision of the conversion factor. Because the conversion rate is a decimal, this task should be used after students have gained some familiarity with ratio and rate reasoning. The decimal has only been carried out to the tenths place to make 1 the calculation more accessible. Many conversions between metric units and standard units are inexact and so the accuracy issue comes up repeatedly.
