What is Subtraction?
Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Time taken by Jorja to run one mile = 9mins 13 secs
= 9 + 13/60 minutes
= 553/60 minutes
Time taken by Miguel to run one mile = 7 mins 38 secs
= 7 + 38/60 minutes
= 458/60 minutes
We have to subtract the time taken by Miguel from the time taken by Jorja to find the additional time etaken by Jorja.
Additional time taken by Jorja = 553/60 minutes - 458/60 minutes
= 95/60 minutes
= 1.583 minutes
= 1 minute 35 seconds.
Hence the additional time taken is 1 minute 35 seconds.

Now, "3 times a certain number is increased by 4" means that the we must add 4 to , in other words, this indicate an addition:
And finally "3 times a certain number is increased by 4 the result is 28" means that is equal to 28. Then the expression is:
To find the number "x", subtract 4 from both sides of the equation:
Dividing both sides of the equation by 3, you get that the number is:
-4 -4
