### Let me go ahead and help you start on these questions...

## Question 1:

From the question we can see that we are talking about 2 jets, but we only are concerned with a single variable. Can you tell me the variable?

Time!

Let t = time that the plane was in flight in hours

This means we can write a single equation, because we only need a single variable! Let's try to relate the distance of each plane to each other.

**Remember: Distance=Rate x Time

## Setting up the Equations:

Plane 1 becomes : 560t rate=560 x time=t

Plane 2 becomes : 750 ______

**try to fill in the blank, think how can we represent 45 minutes later(hint: 45 mins is 45/60 hours)? I'll be happy to check it over if you email me directly or leave a comment here.

## Now What...

After you fill in the blank, it's pretty easy from there...the planes will meet each other when the equation for plane 1 is equal to the equation for plane 2! Set the two equations equal then solve for the variable "t". This is the amount of time it will take for plane 2 to catch up to plane 1! Easy Breezy

## Andrew L.'s Final Thoughts:

After we make some progress on question 1, I'll be happy to walk you through question 2. It is very important that you can understand how one represents "45 minutes later" mathematically. Regent exams love to test this and it will definitely come in handy in more advanced math courses. I look forward helping you understand these questions! Talk to you soon.
