suppose that 30% of the female students and 40% of the male students in a college history class are from a major city. if there are 50 female students and 30 male
students in the class, then of the female students and of the male student are from a major city of the 80 students in the class in total, 7% are from
a major city. the percentage of students from a major city is not equal to the average of 30% and 40%, which is 35%, because the number of female and male students

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
