Anna [14]

Given:

Total number of students = 1400

The ratio of boys to girls is 3 to 4 for the school.

To find:

The number of boys and girls.

Solution:

We have,  Boy : Girls = 3:4.

Let number of boys be 3x and number of girls be 4x.

Total number of students = 1400

3x+4x=1400

7x=1400

Divide both sides by 7.

x=200

Now,

Number of boys =3\times 200=600

Number of girls =4\times 200=800

Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

Answer:

2 hours

Remember that time = distance/rate

The distance you need to cover is 56 miles, while you go 28 miles per hour. Using these, we get this:

time=56/28

time=2
