Question

5. An airplane takes 4 hr to travel a distance of 4100 km. Another airplane travels at a speed

which is 200 km/hr less than first airplane. How long will it take to travel the same distance by
the second airplane?

Answer 1

4.969696 hours

Explanation:

The distance traveled is shown through the following equations

Distance = velocity * time

This means that

4100=velocity*4

This means that ariplane 1 travles at 1025 km/hr

We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr

Now we need to find how long it takes for that plane to travel 4100

So using the same equation

4100=825*time

Divison will tell us that the answer is around 4.9696 hours which is pretty much 5
