Answer to Question #267455 in Real Analysis for Kyami

Question

Create your own or similar real life situation where rational function is applied

Answer 1

Introduction:

Let's move on to the next part and learn more about the speed formula. Speed can be expressed in a variety of ways, including m/s, km/hr, miles/hr, and so on. 

[LT-¹] is the dimensional formula for speed. A body's speed is defined as the rate at which it moves. The formula for calculating a body's speed is as follows: speed=distance÷time

We have to create a real-life condition where rational numbers are applied.

We know that the formula for velocity, when distance is d and time is t, is

$v=\frac{d}{t}.$

Let the distance between my home and my friend's home is 12 km. Let us suppose that, it take t minutes to reach my friend's home. Then the function of velocity is given by

$v(t)=\frac{12}{t}$

This is the required rational function.
