Question 733375
I am having a hard time with ratio / proportions. The question is if an airplane (or aircraft) flies 1260 miles in 3 hours. How far will it travel in 5 hours ? I have looked over in my book examples but its not helping me. I don't know the formula to get to the answer if you could help me out.

The above question is pretty easy !

Let x be the miles traveled in 5 hours.

Therefore:

1260/3 = x/5

Cross multiply the above.

We get:

3x = 6300

x = 2100 miles

Therefore:

Answer: In 5 hours he will travel 2100 miles.
