30/1200 = x/6000
6000/1200 = 5
30 x 5 = 150
Answer:
The answer to your question is: 30 miles can the car travel.
Step-by-step explanation:
Data
gasoline used = 11 1/2 gal
distance = 345 mile-trip
distance travel with 1 gal = ?
Process
Convert 11 1/2 to a improper fraction 11 1/2 = 23/2
Rule of three
23/2 gal ----------------------- 345 miles
1 gal ---------------------- x
x = (1 x 345) / 23/2
x = 345 / 23/2
x = 690/ 23
x = 30 miles
Answer:
300 meters per minute
Step-by-step explanation:
Step 1
Determine the fraction of the total distance for each part of the race.
Given:
1st part of race = 4/9 of total distance
2nd part of race = 2/5 of remaining distance
Step 2
Determine the distance of the third part of the race.
Given:
time = 15 minutes
speed = 300 meters per minute
Step 3
If the third part of the race (which is 1/3 of the total distance) is 4500m, then the distance of the whole race is:
Step 4
Determine the distance of the 1st part of the race:
Step 5
Determine the speed of the 1st part of the race:
Given:
time = 20 minutes
distance = 6000 m
So to find the answer to this, you have to consider that

- half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.
To solve this, first subtract 9 from both side, which leaves you with

and

is the same as

, so to solve this, multiply both sides of the equation by two, resulting in

. SO from this we can conclude that the weekly allowance is $8
