Question

nicole and chanice are building scale models of molecules for chemistry class. nicole can build 6/5 of a scale model in 5/3 hour. it takes chanice 5/3 hour to build 4/3 of a scale model. use unit rates to determine who builds more scale models per hour. 1.3889 models per 1 hour determine nicoles unit rate: hours models specify nicoles rate: 5/3 6/5 determine chanices unit rate: models per 1 hour hours models specify chanices rate: 5/3 4/3

Explanation:

Answer:

Determine Nicole's unit rate:
1.3889 models per 1 hour
Specify Nicole's rate:
\(\frac{6}{5}\) models per hour
Determine Chanice's unit rate:
\(\frac{4}{3}\) models per 1 hour
Specify Chanice's rate:
\(\frac{4}{3}\) models per hour
Nicole builds more scale - models per hour.
