Step-by-step explanation:

7/12

Step-by-step explanation:

1/3 + 1/3 = 2/3

2/3 - 1/3 = 1/3 (Rearrange the denominator together)

= 1/3 + 1/4

(Multiple 1/3 by 4 for the numerator and the denominator)

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
