A 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
k0ka [10]

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

1)Russell from Up has 400 balloons. The balloons are red, yellow, blue and purple. Forty percent of the balloons are red, 5% are
Nastasia [14]

Answer:

Blue Ballon = 16

Yellow Ballon = 23

Green Ballon = 26

Red Ballon = 32

Total puffs = 1000

23y + 16(2y) + 32y + 26(y/2) = 1000

23y + 32y + 32y + 13y = 1000

100y = 1000

y = 1000/10

y = 10

Therefore, russell

filled 10 yellow balloons.
