Juan's time = x
Yumi's time = x + 2
Yumi's distance = 3 miles
Juan's distance = 2 miles
Rate = distance/time
Juan's rate = 2/x
Yumi's rate = 3/(x + 2)
The rates are equal so:
2/x = 3/(x + 2)
2x + 4 = 3x
x = 4 hours
Yumi's time = 4 + 2 = 6 hours
The answer is D.
X^4 is the simplified answer
15% of 425
(15/100) * 425
(3/20) * 425
(3/4) * 85
255 / 4
63.75
4*3^2 = 36. Is that what you meant?
If the question is asking what 36x78 is the answer is 2,808
