S is inversely proportional to t
When s = 0.5, t = 7
Work out s when t = 0.8

Given:

s is inversely proportional to t.

When s = 0.5, t = 7.

To find:

The value of s when t=0.8.

Solution:

s is inversely proportional to t.

      ...(i)

Where, k is the constant of proportionality.

Putting s=0.5 and t=7, we get

Putting k=3.5 in (i), we get

This is the equation of proportionality.

Putting t=0.8, we get

Therefore, the value of s is 4.375 when t=0.8.
