Which of the following correctly describes the variation in the equation r=d/t?

  1. r varies inversely with d and jointly with t
  2. r varies jointly with t and d.
  3. r varies inversely with t and jointly with d.
  4. r varies directly with d and inversely with t.

Verified Answer :

Answer number 3 is correct.

Answer:

Option 3rd is the right choice.

Step-by-step explanation:

Which of the following correctly describes the variation in the equation r=d/t?

Option 3rd is correct - r varies inversely with t and jointly with d

Inversely related means if the value of one entity increases, the value of second decreases and vice versa.

Here, r = d*1/t

So, we can say r = 1/t, this means r is in an inverse relation to t and direct relation to d.

So, option 3rd is the correct choice.
