Answer 5

yes =)

Answer 6

since that's true, you know that she went 9 km in 60min. so you can write a proportion like this: \(\Huge\frac{9km}{60min}=\frac{x}{1min}\) to find how many per minute

Answer 7

mmk and then I cross multiply?

Answer 8

yep

Answer 9

Ok so 9/60x?

Answer 10

just 9/60 will give you how many kilometers in a minute

Answer 11

ok and then I multiply that answer by 5 to get the second answer right?

Answer 12

0.15(5) = 0.75
