0.5 miles/ 10 minutes* (60 minutes/ 1 hour)= 3 miles/hour.
0.25 miles/ 6 minutes* (60 minutes/ 1 hour)= 2.5 miles/hour.
The unit rate of Ron is 3 miles/hour.
The unit rate of Steve is 2.5 miles/hour.
Therefore, Ron walks faster~
The two equations are vertical angle, which would be equal to each other.
Set the equations to equal and solve for x:
5x -10 = 3x +40
Subtract 3x from both sides:
2x -10 = 40
Add 10 to both sides:
2x = 50
Divide both sides by 2:
x = 50 / 2
x = 25
The answer is B. 25
How often do they pay? If they only pay once a year, 90000/100=900. 900 * .52 = 468
