The table below shows the total population of Mexico for specific years. Homework Help ✎

 Year Population(millions) $1900$ $13.6$ $1910$ $15.2$ $1920$ $14.4$ $1930$ $16.6$ $1940$ $19.8$ $1950$ $26.3$ $1960$ $35.0$ $1970$ $50.7$ $1980$ $69.7$ $1990$ $87.8$ $2000$ $100.3$ $2010$ $113.7$

1. Recall that average rate of change is calculated by determining the slope between two points. What is the average rate of change for the population from $1900$ to $1950?$

The average rate of change is the slope between two points.
Calculate the slope between $(1900,13.6)$ and $(1950,26.3)$.
Pay attention to the units.

2. What is the average rate of change from $1960$ to $2010?$

3. Given your answers in parts (a) and (b), for which time period is the population growth rate higher? Explain.
