574.8 miles
Step-by-step explanation:
Given:
An average speed of Wilma from City A to City B = 60 miles per hour
She stayed in City B 15 hours.
An average speed of Wilma from City B to City A = 35 miles per hour.
Whole time taken including 15 hours stay in city B = 41 hours
Question asked:
How many miles is City A from City B ?
Solution:
Total time taken including 15 hours stay in city B = 41 hours
Total time taken on the trip excluding stay in city B = 41 - 15 = 26 hour
Let time taken during from city A to city B =
Time taken during from city B to city A =
As distance traveled from city A to city B is equal to distance traveled from city B to city A:-
And by using :
Distance traveled from city A to city B = Distance traveled from city B to A
=
Adding both sides by
Dividing both sides by 95
Distance traveled from city A to city B =
= 60 9.58
= 574.8 miles
Therefore, there are 574.8 miles from City A to City B.
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have two points (2, 0) and (-2, -4). Substitute:
Therefore we have the equation of a line
Put the coordinates of the point (2, 0) to the equation:
<em>subtract 2 from both sides</em>
