Answer:
Rosa's rate is 6 miles per hour
Step-by-step explanation:
Rosa rides for 3 hours and is 20 miles from her house.
After riding for 5 hours, she is 32 miles away
Let x represents the number of hours
and y represents the number of miles away
(3,20) and (5,32)
rate is the slope
to find rate we find change in miles over change in hours
[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{32-20}{5-3} =6[/tex]
so Rosa's rate is 6 miles per hour
