You multiply fractions simply by multiplying numerators and denominators with each other:

The formula which relates Distance, av.Speed and Time is

The maximal Distance would be covered if the average speed was 6.3 miles per hour.
In that case D=6.3 (mi/h) * 2 h = 12.6 mi
thus, if x represents the number of miles, x≤12.6 mi
Answer: x≤12.6 mi
45000 x 4 = 180,000
180,000 * 5 = 900,000 ml in 5 days
1 liter = 1000 ml
900,000 / 1000 = 900 liters of water
Answer:
x=9 Hope this helps :)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 3x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 3/(-8).
And you get x=9
C = 9/28 = 0.321
