Alex cycles at a speed of 10 miles per hour He cycles 6 miles from home to

Maslowich

If Alex increases his speed by 2 miles per hour from 10 miles per hour he will be 0.01 hrs or 6 minutes faster that is will take 6 minutes less to reach school.

<u>Solution: </u>

Given that

Alex cycles at a speed of 10 miles per hour; Alex cycles 6 miles from home to school.

Need to calculate how much faster will Alex reach to school if he increase its speed by 2 miles per hour . Formula for time is as follows ,

$\text { Time }=\frac{\text { Distance covered }}{\text { speed }}$

Lets calculate time taken by Alex to reach school at normal speed that is 10 miles per our

As distance covered from home to school is 6 miles

Distance covered = 6 miles

Normal Speed = 10 miles per hour

Substituting the given values in formula of time we get

Time taken at normal speed $\mathrm{T}_{\mathrm{N}}=\frac{6}{10}=0.6 \text { hours }$

Now calculate time taken by Alex to reach school when speed is increased by two

Distance covered = 6 miles

Increase Speed = $10 + 2 = 12 \text { miles }$

Substituting the given values in formula of time we get

Time taken at Increased speed $\mathrm{T}_{\mathrm{I}}=\frac{6}{10}=0.5 \text { hours }$

Difference in time taken = $\mathrm{T}_{\mathrm{N}}-\mathrm{T}_{\mathrm{I}}=0.6-0.5=0.10 \mathrm{ hrs }$

As 1 hour = 60 minutes

$\Rightarrow 0.10 \mathrm{hrs}=60 \mathrm{x} 0.10=6 \text { minutes }$

Halle la ecuación del eje x y la ecuación del eje y, usando dos puntos que se encuentren sobre los mismos.

lisov135 [29]

Una linea recta ( cualquier eje coordenado es una línea recta) queda definida si se conocen dos puntos que están sobre ella.

Solución:

Ecuación del eje x y = 0

Ecuación del eje y x = 0

Para darle respuesta a la pregunta podemos seguir el siguiente procedimiento:

Escogemos dos puntos arbitrarios sobre el eje x, por ejemplo

P ( 2 ; 0 ) y Q ( 5 ; 0 ) ( todos los puntos sobre el eje x tienen coordenada y = 0.

Según la cual m = (y₂ - y₁)/ ( x₂ - x₁ ) m = 0

Usamos la ecuación pendiente-Intercepto

y = m×x + b donde m es la pendiente y b el intercepto con el eje y

y entonces tenemos:

m = 0 b ( 0 ; 0 )
Por sustitución en la ecuación pendiente-intercepto

y = 0

Procediendo de forma similar obtendremos la ecuación del eje y

P´( 0 ; 4 ) Q´( 0 : 8 ) entonces

y = m×x + b

En este caso, la pendiente no es definida ( tang 90° ) y b es de nuevo el punto b ( 0 ; 0).

A partir de que todos y cada uno de los puntos sobre el eje y son de valor 0 para x, concluímos que ecuación del eje y es

x = 0
