15. in the given diagram to the right, n || p & k || m. m_10 = (5x + 3)',
m_16 = (7x – 39), and mc15 = (7y + 2)° . find the
values of x, y, m_10, and m_15.

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
