7. In the first race of the season, Carol swam her event in 5 minutes and 15 seconds. Her goal was to be able to swim the same distance in \frac{2}{3} 2 3 the time by the end of the season. If she reaches her goal, how long will it take her to swim the race at the end of the season?

Answer 1

5 minutes = 5*60 = 300 seconds.
300 seconds + 15 seconds = 315 seconds.
(2/3)*315 seconds = 210 seconds = 3 minutes and 30 seconds.
