1. At noon a passenger train leaves the Columbus Railway station and travels due west for 2 hours. At 12:15 PM the same day a second passenger train leaves the same railway station and travels due east
for 1 hour and 45 minutes at a speed 12 km per hour slower than the first passenger train. At 2:00 PM
the two trains were 297.75 km apart. How fast had each train been traveling?

297.75 ans PLS MARK ME AS BRAINLIEST

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
