Answer:
40 miles
Step-by-step explanation:
Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.
We know that 40<em>t</em> is equal to <em>x</em>.
We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).
Solve for t:
40t = 30(t+1/3)
40t = 30t + 10
Subtract 30t from both sides:
10t = 10
Divide 10 from both sides:
t = 1
40t = 40 x 1 = 40 miles
Answer:
<h2> 25 centimeters</h2>
Step-by-step explanation:
Ratio 4:5 means:
width: W = 4x
length: L = 5x
Area of rectangle: A = W×L
Therefore:
500 = 4x×5x
500 = 20x²
50 = 2x²
x² = 25
x = 5
W = 4×5 = 20 cm
L = 5×5 = 25 cm
