Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be x

and total hikers in one group be y

if number of girls and boys in every group is same, then

\frac{21}{x} + \frac{56}{x} = y

\frac{21 + 56}{x} = y\\x*y = 77 ....(1)

from (1) x will either be 11 or 7

for x = 11 the values won't be real.

For x = 7\\y = \frac{77}{7} \\y = 11

so there will be 7 groups with 11 hikers in each groups and every group will have \frac{21}{7} = 3 boys and \frac{56}{7} = 8 girls

The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let a represent the speed of the airplane and b represent the speed of the wind, hence:

(a + b)6 = 2400  

a + b = 400     (1)

Also:

(a - b)7.5 = 2400

a - b = 320   (2)

From eqn 1 and 2:

a = 360 km/h, b = 40 km/h

The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.

So, 4^(1/2) = 2 (or -2)
