Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===

Answer: 0.2308
Step-by-step explanation:
A new bag of golf tees contains 10 red tees,10 orange, 10 green tees, and 10 blue tees. You empty the tees into your golf bags.What is the probability of grabbing out two tees of the same color in a row for you and your partner?
# of ways to succeed:: 4(10C2) = 4*45 = 180 ways
# of random pairs:: 40C2 = 780
P(2 of same color) = 180/780 = 0.2308
Therefore your answer is 0.2308
