Erica can run 1/6 of a mile in a minute. her school is 2/3 of a mile away from her home. at this speed how long would it take erica to run home from school?

D=vt (distance equals velocity times time)

t=d/v, we are given that d=2/3 and v=1/6 so

t=(2/3)/(1/6)

t=(2/3)(6/1)

t=12/3

t=4 minutes.

1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .
