A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?

Answers

Answer:

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Step-by-step explanation:

Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.

car = ( x + 19 ) mph

truck = ( x ) mph

Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:

(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )

Substitute,

( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048

Simplify,

8x + 152 + 8x = 1048

16x + 152 = 1048

       -152     -152

16x = 896

/16     /16

x = 56

Add (19) to find the speed of the car:

truck speed + 19

= 56 + 19

= 75

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Answer:

The truck traveled at 81

mph. The car traveled at 100

mph.

Answers

Answer:

Me ha quedado una cuarta parte de la cantidad inicial, es decir, me he gastado tres cuartas partes de la cantidad inicial comprando crustácea importada en la pescadería y marisquería.

Step-by-step explanation:

Asumamos que hacemos la compra en una pescadería y marisquería. Si la razón inicial equivale a 1, gasta inicialmente la mitad de la razón inicial, luego gasta la mitad de la razón resultante. El gasto se entiende como una forma de sustracción mientras que la sucesión como una multiplicación. Por consiguiente, tenemos el siguiente producto:

[tex]c = \left(1-\frac{1}{2} \right)\cdot \left(1-\frac{1}{2} \right)\cdot c_{o}[/tex]

[tex]c = \frac{1}{4}\cdot c_{o}[/tex]

Donde [tex]c_{o}[/tex] es la cantidad inicial.

Me ha quedado una cuarta parte de la cantidad inicial, es decir, me he gastado tres cuartas partes de la cantidad inicial comprando crustácea importada en la pescadería y marisquería.

Answers

Answer is 14.6. Good luck.

Answer:

14.6

Step-by-step explanation:

For this case we have the following trigonometric relationship:

sine (x) = C.O / h

Where,

x: angle

C.O: opposite leg

h: hypotenuse

Substituting values we have:

sine (20) = 5 / c

Clearing c:

c = 5 / sine (20)

c = 14.619022

Rounding:

c = 14.6 in

Answer:
