Answer:
The train ride is 3.5 hours
Step-by-step explanation:
We know that distance is equal to rate times time
d = rt
We know the distance and the rate
420 = 120*t
Divide each side by 120
420/120 = 120t/120
3.5 =t
The train ride is 3.5 hours

Answer:
Independent events are those events when the happening of one event does not affect the happening the other event.
In the given example we have the following events as independent:
A) A spinner is spun and a coin is flipped
C) Two number cubes are rolled at the same time.
Both these events are independent because the happening of one event does not affect the other in both the cases.
But the options B and D are not independent because in both the cases happening of first event affects the happening of the next event. Therefore, the correct options are A and C.
I think the answer is A, correct me if I wrong !
