The probability that Rahul succeeds at any given free-throw is 70\%70%70, percent. He was curious how many free-throws he can expect to succeed in a sample of 151515 free-throws. He simulated 303030 samples of 151515 free-throws where each free-throw had a 0.70.70, point, 7 probability of being successful. Rahul counted how many free-throws were successful in each simulated sample. Here are his results:

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
