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
Using the Distributive Property
The answer would be 3.
2 *4x = 8x and 2 * 3 = 6, to get 8x 6
The answer is a because we don’t care
