Question

If it takes an airplane 3 hours to fly 3600 miles, how long will it take to fly

5400 miles. Use a decimal for your answer rounded to the nearest tenth.

Answer 1

270 minutes or 4.5 hours

Explanation:

You need to find the unit rate in order to solve this problem with the given information. In order to find the unit rate (in minutes) let's find each minute. Do 3600/180=20. You use 180 because that's the amount of minutes in 3 hours. Then, you take 5400 and divide it by 20 to get 270. Convert back to hours and rounded you get 4.5 hours.
