Answer:

It took 1.2 hours to get to the store

Step-by-step explanation:

Let the time taken to reach the store be t₁

Let the time taken to come back be t₂

Let the speed to and from store = s₁ and s₂ respectively

let the distance to the store = d

To the store:

$speed = \frac{distance}{time} \\s = \frac{d}{t_1} \\t_1 = \frac{d}{s_1}\\t_1 =\frac{d}{4} - - - - - (1)$

Back from the store:

$s_2 = \frac{d}{t_2} \\t_2 = \frac{d}{s_2}\\where:\\s_2 = 6\ miles\ per\ hour\\t_2 = \frac{d}{6} - - - - - - (2)$

We are told that total time (t₁ + t₂) = 2 hours

t₁ + t₂ = eqn (1) + eqn (2)

$\frac{d}{4} + \frac{d}{6} = 2\\Multiplying\ through\ by\ 12:\\3d\ +\ 2d\ =\ 24\\5d = 24\\d = \frac{24}{5} \\d = 4.8\ miles$

∴ length of trip to the store = t₁

from eqn (1)

$t_1 = \frac{d}{4} \\t_1 = \frac{4.8}{4} \\t_1 = 1.2\ hours$

A room that contains 28 square yards was carpeted at a cost of $322. If

ASHA 777 [7]

The cost for carpeting 20 square yards is $230.

Further explanation:

First of all, we will calculate the cost for one square yard then will find the final answer.

So,

Given

Total area = 28 square yards

Cost of carpeting 28 square yards = $322

Cost of carpeting one square yard = 322/28 = $11.5 per square yard

Now to find the cost of carpeting 20 square yards

Cost of 20 square yards = 20*11.5

= $230

The cost for carpeting 20 square yards is $230.
