Answer:
450 feet
Step-by-step explanation:
60ft = 4 seconds
x ft = 30 seconds
(cross multiply)
60 * 30 = 4x
1800= 4x
(divide both sides by 4)
x= 1800/4= 450
Let x = questions with 2 points and y = questions with 4 points;
We solve the equation: x + y = 40 and 2x + 4y = 100;
Then, x = 40 - y;
2( 40 - y ) + 4y = 100;
80 - 2y + 4y = 100;
80 + 2y = 100;
2y = 20;
y = 10;
x = 40 - 10;
x = 30;
