2

Step-by-step explanation:

Hey There!

When it ask for the scale factor its asking for what did you have to multiply the side length by of figure a to get the similar side length of figure b

for example in figure A the base length is 7

to get the the base length of figure B (14) they multiplied the base length of figure A by 2

7x2=14

therefore the scale factor is 2

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
