Question

A jet flies 3,360 miles from New York to Paris in about 2.7 hours. About how many hours would the jet take to fly 5,687 miles from Paris to Rio de Janeiro?

Answer 1

From New York to Paris:
2.7 hours 3,360 miles
From Paris to Rio de Janeiro:
x hours 5,687 miles
-------------------------------------
2.7 : x = 3,360 : 5,687
3,360 x = 2.7 * 5,687
3.360 x = 15,354.9
x = 15,354.9 : 3,360
x ≈ 4.6 hours
