Question 185062
Anita started walking from her home toward the park at 3 p.m.. By 4:30 p.m. she had reached the park, which is 4 miles away from her home. 
Write an equation that relates time x and distance y from home, assuming Anita's speed is constant.
--------------------------------------
Anita DATA:
time = 1 hr ; distance = 4 miles
Equation:
rate = distance/time
r = (4 miles)/(1 hr) = 4 mph
======================================
rate = distance/time
r = y/x
======================================
