Since t and u are inversely proportional, we can set up the equation:
t * u = k
where k is the constant of proportionality.
Given that t = 7 and u = 3, we can substitute these values into the equation:
7 * 3 = k
k = 21
Now, we can use the value of k to find t when u = 21:
t * 21 = 21
t = 21 / 21
t = 1
Therefore, when u = 21, t = 1.
t * u = k
where k is the constant of proportionality.
Given that t = 7 and u = 3, we can substitute these values into the equation:
7 * 3 = k
k = 21
Now, we can use the value of k to find t when u = 21:
t * 21 = 21
t = 21 / 21
t = 1
Therefore, when u = 21, t = 1.
