Answer:
E, needs more info to be determined
Step-by-step explanation:
We know that Kai takes 30 minutes round-trip to get to his school.
One way is uphill and the other is downhill.
He travels twice as fast downhill than uphill.
This means that uphill accounts for 20 minutes of the round-trip and downhill accounts for 10 minutes of his trip.
However, even with this information, we do not know how far his school is.
In order to figure out how far away his school is, we would need more information about the speed at which Kai is traveling.
Simply knowing that he travels twice as fast downhill is not enough.
This question could only be solved by knowing how many miles Kai travels uphill or downhill in a given time.

Answer:
i need points sorry
Step-by-step explanation:
Order set...{160,165,170,240,240,450}
The "mean" is the arithmetic average of the elements...
mean=(160+165+170+240+240+450)/6=237.5
The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.
In this case the number of elements is even and the middle two terms are 170 and 240 so:
median=(170+240)/2=205
The "mode" is the term which appears the most in the set, so in this case:
mode=240
