Flying against the wind, an airplane travels 4620 kilometers in 7 hours. Flying with the wind, the same plane travels 8640 kilom

nordsb [41]

The rate of the plane in still air is 870km/h and the rate of the wind 210km/h.

<h3>What is speed?</h3>

Speed has the dimensions of distance divided by time.

Let Speed of airplane be x km/h and Speed of Wind be y km/h

Speed direction of wind (x+y)

Speed in opposition of wind (x-y)

Now, using speed x time= distance

7( x-y)=4620

(x-y)=4620/7

=660------------------(1)

Similarly,

8(x+y)=8640

(x+y) =8640/8=1080-----------------------(2)

Adding (1) and (2)

2x=1740

x=870 km/h

Subtracting (1) from (2)

2y=420

=>y=210 km/h

So rate of airplane =870km/h

rate of wind=210km/h

Alexus [3.1K]

Answer:

16 blueberries and 4 strawberries

Step-by-step explanation:

Given:

A bowl contains blueberries and strawberries there are a total of 20 berries in the bowl.

The ratio blueberries to strawberries is 4 to 1

Question asked:

How many of each berry are in the bowl ?

Solution:

Ratio of blueberries and strawberries = 4 : 1

Let ratio be $x$

Number of blueberries in the bowl = $4x$

Number of strawberries in the bowl = $1x=x$

As total berries in the bowl are 20 and the bowl contains both blueberries and strawberries in the ratio 4 : 1 :-

$4x+x=20\\5x=20\\$

Dividing both sides by 5

$x=4$

Number of strawberries in the bowl = $x$ = 4

Number of blueberries in the bowl = $4x$ = $4\times4=16$

Thus, there are 16 blueberries and 4 strawberries in the bowl.
