To write and solve:An inequality to find the number of minutes one can spend on each subject.

Answer to Problem 21PTTS
The inequality is
Explanation of Solution
Given information:The maximum time is given = 3 hours.
The time spent on maths is given 45 minutes.
The number of other subjects is given = 4
Also, it is given that the amount of time spent on remaining 4 subjects is same.
Formula used:The concept of forming and solving inequalities is used.
Calculation:
The maximum time is given = 3 hours = 180 minutes.
Let the time spent on other 4 subject be
So, the total time spent is,
And the maximum time is 180 minutes
Hence,
Divide both sides by 4.
Thus, one can spend at most 33 minutes and 45 seconds on 1 subject.
