The equation t=15d is a proportional one. The variable t varies proportionately with the variable d. As t increases, d increases as well. Hope this answers the question. Have a nice day. Feel free to ask more questions.

Answer:

t varies  proportional to d

Step-by-step explanation:

Is [tex]t=15d[/tex] proportional or not

In the given equation , t is the output variable and 'd' is the input variable

the value of 't' depends on the value of 'd'

When we increase the value of 'd', the value of 't' will increase

When output variable increases when input variable increases then they are in proportional

[tex]t=15d[/tex]

t varies  proportional to d
