in some cases we use dv/dr to find speed and in some cases we use v/r which 1 will be more appropriate to use?

DV/DR and V/R are two different methods used to calculate speed. DV/DR stands for distance divided by time, while V/R stands for velocity divided by rate. While both methods can be used to find speed, DV/DR is used for constant speed situations while V/R is used for changing speed situations.
To calculate speed using DV/DR, you need to know the distance traveled and the time it took to travel that distance. Simply divide the distance by the time to get the speed in units of distance per time (e.g. miles per hour).
To calculate speed using V/R, you need to know the velocity (speed and direction) and the rate of change. Simply divide the velocity by the rate of change to get the speed in units of velocity per rate of change (e.g. meters per second per second).
The method you should use depends on the situation. If the speed is constant, use DV/DR. If the speed is changing, use V/R. It's important to understand the concept and choose the appropriate method to get an accurate calculation.
Yes, you can use both methods in the same situation to verify your results. However, it's important to understand when to use each method and know which one is more appropriate for the given situation. It's also important to ensure that your units are consistent when using both methods.
