Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2 3 of the way there.

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2/3 of the way there. How many more hours does Liza have to drive?

Answer:

Liza need to drive 2 more hours to reach her sister house

Solution:

Given that Liza is driving to her sister's house 360 miles away

So total distance = 360 miles

After 4 hours, Liza is 2/3 of the way there.

$\frac{2}{3} r d \text { of total distance }=\frac{2}{3} \times 360=240$

So Liza has covered 240 miles in 4 hours

Let us find the speed

The relation between distance and speed is given as:

$speed = \frac{distance}{time}$

$speed = \frac{240}{4} = 60$

Thus speed = 60 miles per hour

Assuming speed is same throughout the journey, let us calculate the time taken to complete remaining distance

Remaining distance = 360 - 240 = 120 miles

Now distance = 120 miles and speed = 60 miles per hour

$time taken = \frac{distance}{speed}\\\\time taken = \frac{120}{60} = 2$

Thus Liza need to drive 2 more hours to reach her sister house

Answer:

Your answer should be 15.905625, if it's not 15 percent off per pound.

Step-by-step explanation:

Multiply 4.99 x 3.75 then multiply that answer (18.7125) by .15

That will leave you with 2.806875, which then you subtract that from 18.7125

That will give you your answer, 15.90...

Vanyuwa [196]

Price, when purchased online: 1.30($160)
Price, when purchased at superstore: 1.40($160)

Difference in prices: 1.40($160) - 1.30($160) = 0.10($160) = $16

A higher markup brings a higher retail price.

They are both right triangles so we can use the Pythagorean

theorem to solve.

6. B = sqrt(15^2-9^2)

B = 12 mm

7. B = sqrt(26^2-10^2)
