Ok so we know it took 4 hrs and 15 minutes, which is the same as 4.25 hrs so we divide 1114 by 4.25 which is 262.118. The average speed of the plane is 262 mph.

Then we just have to multiply 262 by 1.6 to get the speed in kph. That equals 419.2. That means the average speed was 419 kph. Hope that helps!

The answer is going to be 25 2/5.
Steps i used to get the answer
I compared   25 3/8 and 25 2/5.    I made the fractions into common denominators. so that would be 40. so i change the fractions which it would look like this   25   15/40  and 25 16/40. So now you compare 25 16/40  would be greater than 25 15/40. hope that helped

PSYCHO15rus [73]
2x - y = 5
x + 3y = 7

I'm assuming you mean the coefficient matrix.
\left[\begin{array}{ccc}2&-1\\1&3\end{array}\right] =(2)(3)-(-1)(1)=6+1=7
