Question

The distance "d" you bike varies directly with the amount of time "t" you bike. Suppose you bike 13.2 miles in 1.25 hours. What is an equation that relates "d" and "t"? What is the graph of the equation?

Answer 1

\[d = kt\]where
"k" is a constant.

Answer 2

whatever the value of "k" will be, it will be the slope of the line.

Answer 3

d = kt


13.2 = k(1.25)


13.2 = 1.25k


13.2/1.25 = k


10.56 = k


k = 10.56


So the equation is d = 10.56t
