Step-by-step explanation:
None necessary.
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.
950-35x=600. X=10. If Ken has 950 dollars in his account. and he withdraws 35 dollars each week then he can keep this pattern going until the 10th week because 950-600 is 350 and 350 divided by 35 is 10. At the end he will have 600 dollars.
