The first thing we must do is convert kilometers to meters. We will do this by multiplying by 1,000, since 1 km corresponds to 1,000 meters.
- 80*1000 = 80,000
- 120*1000 = 120,000
Now that we've done that, let's divide the values by 3,600, because an hour is 60 minutes, and each minute is 60 seconds, so 60*60 is 3,600.


Hence, 80 km/h = 22.22 m/s, 120 km/h = 33.33 m/s
Answer:
Step 4.
Step-by-step explanation:
To isolate the x variable, she subtracts 8 from both sides making it another subtraction property of equality justification.
X=1, y=-2--------------------------
17/16 is the answer since 1/2 is equal to 8/16. 8+9 is 17
