Jim walks 2 miles in an hour. It takes him 3 hrs to walk 6 miles.
a. How far would you expect him to walk in 5 hours?
b. How long would you expect him to take to walk 4 miles?
c. What is the equation you can use if X=hours and Y=miles?

in 5 hours he would walk 10 miles. It would take him about 2 hours to walk 4 miles

Step-by-step explanation:

Since he walks 2 miles an hour, you can multiply 5 by 2 in order to get 10 miles. Use this same strategy for the 4 miles except reverse, divide 4 by 2, 2 hours.  

An equation you can use is, Y = ( X ) x 2

d. vertex
