Question

The relationship between distance travelled, d, and time, t, can be represented by a linear relation. In 56 minutes, a person

runs 6 miles. In 104 minutes, the same person runs 10 miles. An equation that represents this linear relation is?

Answer 1

`d=(t)/(12)+(4)/(3)`

Explanation:

The average rate of change is (10-6)/(104-56) = 1/12.

So, the equation is of the form d = t/12 + c for some constant c.

Substituting in d=6 and t=56 gives that c=4/3.

So, the equation is

`d=(t)/(12)+(4)/(3)`
