Answer:

correct answer is option D

Step-by-step explanation:

assume the speed of the unicorn for the first time to cover 50 mile be 'x'

we know,

distance = speed × time

50 = x × time

t₁ = 50 / x...............................(1)

when unicorn travel 300 mile with speed of '3x'

distance = speed × time

300 = 3 x × time

t₂ = 100/ x...............................(2)

dividing equation (2)/(1)

$\dfrac{t_2}{t_1} = \dfrac{100/x}{50/x}$

t₂ = 2 × t₁

hence, the time will be twice the first one.

correct answer is option D

Darren bought some paint. He used 2 1/4 gallons painting his living room. After that, he had 3 5/6 gallons left. How much paint

Otrada [13]

Answer: $6\frac{1}{12}\ gallons$

Step-by-step explanation:

We can make the conversion from mixed numbers to improper fractions:

Multiply the whole number part by the denominator of the fraction.
Add the numerator of the fraction and the product obtained (This sum will be the new numerator).
The denominator is the same.

Then:

$2\frac{1}{4}=\frac{(2*4)+1}{4}=\frac{9}{4}\\\\3\frac{5}{6}=\frac{(6*3)+5}{6}=\frac{23}{6}$

We need to add the fractions in order to calculate the amount of paint Darren bought. Since the denominators are differente, we must find the Least Common Denominator (LCD):

$4=2*2=2^2\\\\6=2*3\\\\\\LCD=2^2*3=12$

Then:

$\frac{9}{4}+\frac{23}{6}=\frac{27+46}{12}=\frac{73}{12}\ gallons$

To convert this improper fraction to a mixed number:

When you divide 73 by 12 you get a quotient of 6. This will be the whole number.
The remainder obtained is 1. This will be the numerator of the fraction.
The denominator does not change.

Then:

$\frac{73}{12}\ gallons=6\frac{1}{12}\ gallons$
