Answer:
25 liters of petrol
Step-by-step explanation:
78 km = 6 liters
So the ratio is 78:6
Let's find the distance per liter:
78/6 = 13
So you travel 13 km per liter
To find the amount of liters for 325 km, you divide 325 by 13:
325/13 = 25
You would need 25 liters of petrol to travel 325 km.

Answer:
55 miles
Step-by-step explanation:
x=the number of miles per hour
130(Miles)/150(minute) = x(Miles)/60(Minuet)
150x=2800
7800/150=52
Answer:
6
Step-by-step explanation:
Inverse proportion.
z = k/w
z = 3, w = 4
Solve for k constant.
3 = k/4
(4)3 = (4)k/4
12=k
The value of k constant is 12.
z = k/w
Put w as 2 and k as 12 and solve for z.
z = 12/2
z = 6
The value of z when w equals 2 is 6.
