If you drove for 425 miles at 60 mph, you would get there in 7 hours and 8-ish minutes. 425 divided by 60 is 7.08333333333333.

Answer:

V = d / t  or  t = d / V

where

V = speed

d = distance

t = time

t = 7.08 hours

Step-by-step explanation:

In the field of Physics, the concept of "Speed" is defined as the vector magnitude - that is, it has a length and orientation - by means of which the distance traveled by an object or person in a time is expressed determined.

It is universally expressed with the capital letter V, while its measurement is usually measured in meters per second, based on the International System of Units. Likewise, it should be clarified that this measure should not be confused at any time with the Acceleration. To better explain this last point, it is necessary to clarify the speed refers to the rate of change of the position that a specific object has in a given unit of time, while acceleration refers to the rate of change experienced by the speed per unit of time.

If use the next equation:

t = d / V

t = ? is the incognita

d = 425 miles

V = 60 mph

So:

t = 425 miles / 60 mph

t = 7.08 hours

Universal Pet house sells vinyl doghouse and treated lumber doghouses. It takes the company 5 hours to build a vinyl doghouses a
LuckyWell [14K]

Answer:

The system of equations is :

Equation 1- 5x+2y=50

Equation 2- x+2y=30

Number of vinyl doghouse = 5

Number of treated lumber doghouse =12.5

Step-by-step explanation:

Let x be the number of vinyl doghouses

y be the number of treated lumber doghouses

→If it takes the company 5 hours to build a vinyl doghouses and 2 hours to build a treated lumber doghouse. The company dedicates 50 hours every week towards assembling and painting doghouses.

Equation 1- 5x+2y=50

→It takes an additional hour to paint each vinyl doghouse and an additional 2 hours to assemble each treated lumber doghouse. The company dedicates 30 hours every week towards assembling and paining dog houses.

Equation 2- x+2y=30

→When we solve these equation we get the number of  vinyl doghouse and treated lumber doghouse.

Subtract equation 2 from equation 1

5x+2y-x-2y=50-30

4x=20

x=\frac{20}{4}

x=5

Put value of x in equation 2

x+2y=30

5+2y=30

2y=25

y=\frac{25}{2}

y=12.5

Therefore, number of vinyl doghouse = 5, number of treated lumber doghouse =12.5
