Ahayride costs $8 per person, and there is a 25% discount for children, students, and senior citizens. if there are (p) people who do not qualify for the discount and (s) people who do qualify, which equation can be used to calculate the revenue (r)? a r = 8p - 6s b r = 8p + (0.75)(8)(s) c r = 8p + 0.75s d r = 8p + (0.25)(8)(s)

the answer for this question is D

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
