Step-by-step explanation:
We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.
We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:
To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.
Upon combining like terms we will get,
Therefore, the total distance traveled in terms of x will be .

Step-by-step explanation:
Given : The total number of programmers in the company = 30
The company wants to select a group of 6 programmers to work on a particular project.
Since the order of selecting them does not matters , therefore we use combinations.
The number of combinations of r things taken from n things is given by :-
here, n= 30 and r= 6
So the number of different ways to form they could select a group of 6 would be
i.e. Total ways =593775
In terms of factorials , the number of total ways to form they could select a group of 6 is .
