There are 7 days in a week so
1.5 x 7 = x
x = 10.5 km
to go to meters we must multiply by 1000
10.5 x 1000 = 10500 meters
<h3>
Answers:</h3>
Variation Constant: k = 7/6
y = 245/6 when x = 7 and z = 5
====================================
Explanation:
"y varies jointly as x and z" means that y = kxz
We have (x,y,z) = (4,14,3) as one triple, so,
y = kxz
14 = k*4*3
14 = 12k
12k = 14
k = 14/12
k = 7/6 is the variation constant
The equation goes from y = kxz to y = (7/6)xz
----------------
Plug in x = 7 and z = 5 to find y
y = (7/6)xz
y = (7/6)*7*5
y = (7/6)*(7/1)*(5/1)
y = (7*7*5)/(6*1*1)
y = 245/6
Answer:
The constant of proportionality k = 11.5.
The equation will be: 
Step-by-step explanation:
If x represents number of hours than y represents miles
We are given:
x y
4 46
5 57.5
6 69
The constant of proportionality can be found using formula: 
Putting values and finding k
x y k (
)
4 46 11.5
5 57.5 11.5
6 69 11.5
So, the constant of proportionality k = 11.5
Now, The equation will be:

So, the equation will be:
