Where in the world would you like to travel, and how might you use your math education to plan your travels? If you visit nearby locations you might travel by car and use math skills to determine distance, time, and mileage. If you fly or travel by train to faraway places you will need math to schedule flight lengths, take-off and landing times.

As a company who provides math help for kids, we’re interested in spreading great math tutoring all over the world. One way we do that is through our weekly word problem challenges, which allow you to take your tutoring in math with you wherever you go! This week’s word problem gives students the opportunity to practice elementary math skills such as time, addition, and subtraction in a real-world situation.

Go ahead and try solving the question. We know you can do it! When you're ready, look below to check your solution against ours.

Question: Tiffany arrived at the airport at 3:50 PM. Her flight was supposed to leave at 5:15 PM, but it was delayed for 2 hours. How long was Tiffany at the airport before her flight left?

Solution: The plane left 2 hours after 5:15 PM, which means it left at 7:15 PM. It is 25 minutes from 3:50 PM to 4:15 PM and then it is 3 hours from 4:15 PM to 7:15 PM, so the total time Tiffany was at the airport was 3 hours and 25 minutes.

Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
