In one day, annie traveled 5 times the sum of the numbers of hours brian traveled and two. together they traveled 20 hours. find the nurmber of hours each person traveled.

5B + B = 20

6B = 20

B = 20 / 6  

= 10/ 3 hrs

A = 5 ( 10/3 + 2)

 = 5 (16/3)

 = 80 / 3 hrs  

 Brian traveled 10/3 hours and Annie traveled 80/3 hours.

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

definitely a. the others have almost all data points on one side of the line.
