Since the question is asking "How many hours will the plane fly," convert 11miles per minute into x miles per hour.

Shadow:

You do that by the following expression $\frac{ 11miles }{ minute } \times \frac{ 60minutes }{ hour } = \frac{ 660miles }{ hour }$

Minutes cancel out, giving you hours. Now we have the speed of the plane. Now lets figure out the total distance traveled. There are 6 trips, with each trip being 500 miles each. Total distance traveled = 6 x 500 = 3000miles

Now that we have the speed of the plane, and the total distance traveled, do you have an idea of how we would get the time it took for the plane to travel that distance? @cookiemonster

Shadow:

Well, for this, we can utilize an image. It illustrates the following formulas. In order to find distance, put speed besides time $Distance = Speed \times Time$ To find speed, put distance over time $Speed = \frac{ Distance }{ Time }$ To find time, put distance over speed $Time = \frac{ Distance }{ Speed }$

Here, we want to solve for time, so we put distance over speed. Let T = time $T = \frac{ 3000miles }{ 660miles/hour }$ $T = \frac{ 3000miles }{ 1 } \times \frac{ hour }{ 660miles }$ $T = \frac{ 3000hours }{ 660 }$ $T = 4.5hours$

You actually get the fraction 50/11, but I do not know what your teachers policy is for decimal places, so I went by sig figures.
