Jessica is walking home from a friend’s house. after 2 minutes she is 1.4 miles from home. twelve minutes after leaving, she is 0.9 miles from home. what is her rate in miles per hour?

let's say 12 min - 2 mins = 10 mins

and 1.4 mile - 0.9 miles = 0.5 miles

Jessica takes 10 mins to walk a distance of 0.5 miles

=> 10 mins*6 = 60 mins = 1 hour

=> 0.5 miles*6 = 3 miles

her rate is 3 miles per hour

Jessica's rate is 3 miles per hour.

Step-by-step explanation:

Jessica is walking home from a friend's house.

After 2 minutes she is 1.4 miles from the home and after 12 minutes she is 0.9 miles away fro her house.

Her rate will be =

=

=

= 0.05 miles per minute

Now we will convert timings from minutes to hour.

Or = 0.05×60  

= 3 miles per hour

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
