1/2
Step-by-step explanation:
since 10petrols=1 oil
therefore 5petrols=1/2
Answer:
20
Step-by-step explanation:
pilot flew a 400-mile flight in 2.5 hours flying into the wind . Flying the same rate and with the same wind speed, the return trip took only 2hours with a tailwind
The speed can be defined as the ratio distance over time, but in this case the pilot is flying at the speed of the plane as well of speed of the wind. We can denote speed of plane as "s" and speed of the wind as "k"
Then the speed of the plane=(s-k) this is because it is moving in the opposite direction of the wind.
But From the question, the plane distance=400mile and the corresponding time =2.5 h
Then the speed of the plane=(s-k) =400mile/2.5
=160mph
By the time it return from trip, the speed the plane flew with is (s+k) because the wind is at the rear.
From the question, the plane distance=400mile and the corresponding time =2 h
Then (s+k)= (400/2)
(s+k)=200mph
The answer for this problem is 0
Answer:
Yes
Step-by-step explanation:
This is called Box and Whiskers or box plot.
The box in the middle contains 50% of data and the right end of the box is 75th percentile, you are correct.
25% of data is distributed to the left and 25% of data to the right of the box that is in the middle.
