I have a very relaxing break playing Solitaire as often as I could. After playing 500 games, my success rate is 49%. How many ga
lukranit [14]

Answer:

5 more games to be won for the 50% success rate.

Step-by-step explanation:

Total number games played = 500

Number of successful games = 49% of 500

                                                 = 500 × \frac{49}{100}

                                                 = 245

Number of successful games for the success of 50% = 500 × \frac{50}{100}

                                                                                        = 250

Therefore, number of game you have to win more = 250 - 245

                                                                                    = 5 games

Sound travels through sea water at a speed of about 1500 meters per second. At this rate, how far will sound travel in 2 minutes
Mariulka [41]

Answer:

180,000 m

Step-by-step explanation:

There are 60 seconds in a minute, so:

2 min × 60 s/min = 120 s

Distance = rate × time

d = 1500 m/s × 120 s

d = 180,000 m
