<span>6x+9y = 10500
x+y = 1480
Using elimination I get:
6x + 9y = 10500
-6x-6y = -8880
Add the 2 equations and I get 3y = 1620
Divide both sides by 3 and I get y = 540
Substitute that back in to 6x+9y = 10500.
I get that 6x+9*540 = 10500
9 * 540 = 4860
Subtract 4860 from both sides and I get 6x = 5640
Divide both sides by 6 and I get x = 940
So there must have be 940 children and 540 adults</span>

First you need to find how far he can run in one minute. To do that divide 18.4 by 5. I got 3.68.
Then, multiply that by 23 to see how far he can run in 23 minutes. I got 84.64
Well 25 seats are available so 25/250 equals 0.1 or
10%
