Answer:
12
Step-by-step explanation:
you divide 36 by 3 and get z = 13
Answer:
6
Step-by-step explanation:
Y is directly proportional to 1/x2
Y = k/x2
Where k is the proportionality constant
y1*(x1)2 = y2*(x2)2
7.2*(10)2 = 20*(x2)2
x2 = sqrt(36)
X = 6
The first thing we must do is replace y = 1 in the equation and clear the value of x:
1 = 7.5x
Clearing x:
x = 1 / 7.5 = 0.13 h
Then, you should keep in mind the following conversion:
1h = 60min
x = (0.13) (h) * (60/1) (min / h) = 7.8 min
answer:
It will take 7.8 minutes to travel 1 mile
