Answer:constant of variation = 6/5

Step-by-step explanation:

t varies inversely as r

Let k be the constant of variation

t = k/r

t = 6 and r = 5

Is this right? i’m not sure

My only issue is that it says numbers between. It does not say including. Therefore, I think you want to use > and < instead of the ones with equals signs attached.
