Question 1197634: (I DON'T KNOW IS IT CORRECT OR NOT,if you can help me,it will be thankfull.
1st question:
An airplane consumes 140L of gasoline in flying 680km.Under similar conditions,how far can it fly on 240L?
Methods I tried :140L/680km=240L/? km ans:1166km
2nd question:
When a bullet
3rd question:
An electric current
4th question:
The velocity v of a
5th question:
The time t required
thanks for answering.

You can put this solution on YOUR website! Some separate questions. Only helping with this one:
---

---
Set up a proportion as the question and description go.
airplane does this consumption rate:  .
Question asks for how many kilometers for a fuel quantity of 240 liters.
Solve this for d.

Also for the first question only....
The other tutor sets this up formally as a proportion:
That equation is easily solved by cross multiplying.
There is less work required to get the answer if you use the direct proportion information in a different way. The "new" distance is the old distance, multiplied by the ratio of the numbers of liters:
The calculation ends up being the same, but you save one step in setting up the problem....

There are two issues:- You posted multiple problems. Ideally you should post one at a time.
- The questions 2 through 5 are incomplete, which makes them impossible to answer.
But I do appreciate you showing your work and thought process on problem 1.
It is a correct line of thinking.
x = distance it travels using 240 L of gasoline
(140 L)/(680 km) = (240 L)/(x km)
140/680 = 240/x
140x = 680*240 .... cross multiply
x = 680*240/140
x = 1165.71428571429
which is approximate. Round that however you need to.
