The answer is what the brainliest answer person (anklebreaker05) put: 1/3.
Well by now you guys already figured out this was the wrong answer before. (Based on the rating I got) :\
GUESS WHAT?
I'm not 20!! I dont know why they did that (on my profile). You'd think that I would get it correct cause im "20." Nope. We were about to learn about ratio and stuff until the coronavirus comes and then school is closed for more than months so we didn't really learn about it with the teacher. It is usually from the videos but people can't understand everything. I wanna delete this now, you know. But I don't know how to and I can't and after I re-edit this I probably don't even want to delete it. Okay, my answer was wrong. sheeshhhh.
Answer:
Jo started decelerating at the 10th minute
His average speed for the last 30 minutes of the journey is 4/30 km/minute
Step-by-step explanation:
To get what Jo did at 10 minute, we look at the graph.
At the 10th minute, we can see that we have a sharp turn from the top to the zero position at the 20th minute
so we can say that Jo started deceleration at the 10th minute
For the last 30 minutes of the journey, he travelled a distance of 4km
So, mathematically, his average speed will be;
Distance/ time = 4km/30 minutes = 4/30 km/minute
Answer:
471
Step-by-step explanation:
the radius is half of the circumference
Distance traveled by an airplane in 7 hours = 4,914 kilometers
We have to determine the unit rate for kilometers per hour.
So, distance traveled by an airplane in 1 hour = 
= 702 kilometers.
So, an airplane will travel 702 kilometers in an hour.
Therefore, the unit rate for kilometers per hour is 702 km per hour.
