Answer:
1.6 hours
Step-by-step explanation:
Their separation speed is 95 +105 = 200 miles per hour. The time required for the given distance is ...
time = distance/speed
time = (320 mi)/(200 mi/h) = 1.6 h
It will take 1.6 hours for the trains to be 320 miles apart.
If 3 of spades is drawn...and not replaced..
P(next card is spade) = 12/51
P(next card is a king) = 4/51
12/51 + 4/51 = 16/51
