You will read for 45 minutes if your brother reads for 15 minutes.
<em><u>Explanation</u></em>
You decide to read 30 minutes longer than your brother reads.
If your brother reads 
number of minutes, then 30 minutes longer than minutes means 
minutes.
As the number of minutes you read is 
, so the equation will be: 
When your brother reads for 15 minutes, then we will just <u>plug 
into the above equation</u>. So.....
So, you will read for 45 minutes if your brother reads for 15 minutes.
Speed traveling west = x - 10 km /hr
275 / ( x-10) - 300 / x = 1/2
275 *2x - 300 (x-10)*2 = ( x-10) *x
550x - 600x +6000 = x^2 -10x
x^2 +40x - 6000 = 0
( x -60) ( x+100) = 0
x = 60
ANSWER East = 60 km/ hr West = 50 km /hr
CHECK
300 /60 = 5 hours
275 /50 = 5.5 hours
Slope formula: Change in y over change in x
Change in y: +4
Change in x: +5
Slope: 4/5
