Typically if it is a linear function then it doesn't matter. However if it is a quadratic, cubic, and so on and so forth....(x^{2},x^{3},x^{4}) you may want to used the distance formula if you are not given any other points (with the exception of the vertex, asymptote or roots... etc).

When fritz drives to work his trip takes 40 ​minutes, but when he takes the train it takes 30 minutes. find the distance fritz t
sweet-ann [11.9K]
Distance = rate*time

convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs

Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.

We know the time we know the speed, Next
distance that Fritz drive = \frac{2}{3}s
distance the train travel = \frac{1}{2}(s+15)

The question: Assume that the train travels the same distance as the car
==> \frac{2}{3}s = \frac{1}{2}(s+15)
==> \frac{2}{3}s = \frac{1}{2}s + \frac{15}{2}
==> \frac{2}{3}s - \frac{1}{2}s = \frac{15}{2}
==> \frac{1}{6}s = \frac{15}{2}
==> \frac{6}{1} * \frac{1}{6}s = \frac{15}{2} * \frac{6}{1}
==> s = 45 
Now we know that Fritz drive at 45 mph, 
distance = \frac{2}{3} * 45 = 30 miles
