Eugene, Brianna, and Katie are going on a run. Eugene runs at a rate of 4 miles per hour. If Brianna runs 2/3 as fast as Eugene, and Katie runs 7/5 as fast as Brianna, how fast does Katie run?

Brianna is  2/3 as fast as  Eugene     2/3 * 4 m/h

 

Katie is  7/5 as fast as Brianna      7/5  *     2/3*4  = ......   m/h
