A high-speed train travels 480 km from Paris to Grenoble, France, at an average speed of 180 km/h. How long will it take the tra

Mekhanik [1.2K]

Speed of the train = 180km/hr
Now, distance from Grenoble to Paris = 480 km
Speed = Distance/Time

We know the speed and distance.So, from this we can find time :)
180 km/hr = 480 km /Time
Time = 480/180 = 2.66 hrs ≈ 2.7 hr
Therefore, the answer is D.2.7 hr

Answer:

y = 2 ( x − 1 ) ^ 2 + 2

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (1,2)

h=1, k=2

y = a ( x − 1 ) ^ 2 + 2

sub ( 3,10)

10 = a (3 - 1)^2 + 2

a=2

y = 2 ( x − 1 ) ^ 2 + 2

Apply the distributive property to create an equivalent expression.

Bumek [7]

Given:

The expression is

$(1-2g+4h)\cdot 5$

To find:

The equivalent expression.

Solution:

Distributive property of multiplication over addition is

$a(b+c)=ab+ac$

Where, a, b and c are real numbers.

We have,

$(1-2g+4h)\cdot 5$

Using distributive property, we get

$=(1)\cdot 5+(-2g)\cdot 5+(4h)\cdot 5$

$=5-10g+20h$

Therefore, the expression $5-10g+20h$ is equivalent to the given expression.
