Answer:
The equation is 
Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be

Hence, equation representing the proportional relationship will be 
It’s y = 1/8x - 3, so the first answer
Is it a multiple choice question? I mean, 10/80?..
