Pls confirm if both the below formula is correct :
1. Rate*time = distance, where rate is expressed as distance per unit time
2. Rate*distance= time, where rate is expressed as time per unit distance

Hi Kshitij89,
This is a bit worrisome that you are asking about these formulas. You don't need to remember and you shouldn't rely on these formulas.
The dependence on formulas indicate that you probably don't understand the basis of these formulas because once you understand the basis or the fundamentals, the need for the formulas goes away.
We know that rate in this question is used as a synonym for speed.
We know that speed = distance/time
So, distance = speed*time OR rate*time
If you change the definition of rate, of course the formula will change. However, for sure, you don't need to remember the formula, you just need to understand the basis from where the formula is coming from.
For example, the formula: distance = rate*time is coming directly from the definition of speed (or rate). Once you understand this, you don't need to remember this formula.
You just need to know speed is defined as distance/time and I think remembering this would be very natural to you unlike other formulas.
Math is about common sense and an interpretation or representation of reality. It is not at all about dead formulas and equations.
