Answer:
I believe the answer is 13.3
Step-by-step explanation: So Peter has gone 13.5 hours to reach his destination. If he is traveling at the speed of 30 km per hour. Per is your key word. So you put the problem in a ratio. km would be at the bottom and hours would be at the top. 13.5/30 (imagine this as a ratio). Then for Paul, he has gone 6 hours to reach his destination. We don't know how fast he was going, so it would be a variable. Let's use k for kilometers. Paul's ratio would be 6/k. So now we have 13.5/ 30 = 6/k. Now we can use cross products. 13.5×k= 13.5k. 30×6=180. Now we have 180 = 13.5k. We do 180÷13.5. (because 13.5 and k are being multiplied). So 13.3=k.
I hope this helps!
