A scientist is studying a certain type of bacteria. She starts with only 1 bacteria and observes that the number of bacteria doubles every hour. Which equation can be used to find the number of hours, x, it will take for the population to reach 8,192 bacteria? A. 8,192 = 2x
B. 8,192 = x2
C. x = 8,1922
D. x = 28,192

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
