Answer:
y = 7x
Explanation:
Given that;
You run 9.1 miles in 1.3 hours at a steady rate
Distance y = 9.1 miles
Time x = 1.3 hours
The relationship between the distance y and the time x is the speed v;
Distance = speed × time
y = v×x ......1
v = y/x
Substituting the given values;
v = 9.1/1.3
v = 7 miles/hour
To derive the equation that represents the proportional relationship between the x hours you run and the distance y in miles that you travel. We substitute v = 7 into equation 1;
y = 7x
