The rate(speed) is 1 3/5

We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr

Substitute

4/5= 1/2t

Multiply 2 on both sides
2* (4/5)=(1/2)t * 2

8/5=t

We can simplify this to 1 3/5

givi [52]

Answer:

Step-by-step explanation:

Convert mixed fraction to improper fraction. Then use KCF method

Keep the first fraction.

Change the division operation to multiplication.

Flip the second fraction

$5\frac{1}{5}=\frac{26}{5}$

$5\frac{1}{5}$ ÷ $\frac{1}{4}$ = $\frac{26}{5}$ ÷ $\frac{1}{4}$

$= \frac{26}{5}*\frac{4}{1}\\\\= \frac{26*4}{5}\\\\=\frac{104}{5}\\\\=20\frac{4}{5}$

Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?

eduard

Answer: 14 gallons

Step-by-step explanation:

Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.

Then, based on the information given in the problem, you can write the following expression:

$\frac{1}{5}x+7=\frac{7}{10}x$

Therefore, when you solve for x, you obtain the following result:

$\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14$
