On a bicycle, Anna rides for 4 hours and is 38 miles from her house. After riding for 7 hours, she is 65 miles away. What is Anna's rate? miles per hour

1 hour = 9.5 miles

Step-by-step explanation:

just divided 38 4 times : )

also depends on how fast is she running in miles per hour? this task is to give students experience in reasoning with equivalent ratios and unit rates from both sides of the ratio.

Step-by-step explanation:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
