Answer:

0.9km/minute

or

54km/hour

Step-by-step explanation:

  • Average speed in km/minutes

18km in 20 minutes = 18km/20min

18km/20min = 0.9km/min

  • Average speed in km/hour

1 hour = 60 minutes

20 minutes = 20/60 = 0.3333 hours

18km/20mins = 18km/0.3333hours = 54km/hour

Lostsunrise [7]

Answer:

7.2 + 0.8w

Step-by-step explanation:

combine like terms. Like terms have same variable with same power.

2.2w and (-1.4w) are like terms & 4.8 and 2.4 are like terms.

4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w

                                      = 7.2 + 0.8w

kupik [55]

Answer:

2/15

Step-by-step explanation:

There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.

4/10 x 3/9 = 2/5 x 1/3 = 2/15

I hope this helps :)

Edit: Messed up the multiplication, whoops!
