D. 14, 21, 32, 38

C. 7, 14, 21, 28

Step-by-step explanation:

We want to find the multiples of 7

7*1= 7

7*2 = 14

7*3= 21

7*4 = 28

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
