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
Prime factorization for 600 is 2^3 times 3 times 5^2
Answer: 3854927
Step-by-step explanation: Becuase I smart
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substituting values
=
( cross- multiply )
21x = 7(24 - x) ← distribute
21x = 168 - 7x ( add 7x to both sides )
28x = 168 ( divide both sides by 28 )
x = 6 → C
