Let the speed of Brian = X
Brian drove at X miles per hour for 4 hours
Jake drove at X-15 for 4 hours
Set up an equation to get:
4x + 4(x-15) = 500 miles
Simplify:
4x + 4x -60 = 500
8x - 60 = 500
Add 60 to both sides:
8x = 560
Divide both sides by 8:
X = 560/8
X = 70
Brian's speed was x = 70 miles per hour.
Jake's speed was x - 15 = 70-15 = 55 miles per hour.

where is option...........??
Answer: Its very simple to solve slopes
Step-by-step explanation:
All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
Yes it is the answer that is last on the list because it is that answer
