Bogdan [553]

Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.
So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour
Jazmeen can walk 1.25 miles in one hour.

The ratio of boys to girls in a group is 6:1. If there are 45 more boys than girls, work out how many people there are in total.

labwork [276]

Number of boys is 54 and number of girls is 9.

Step-by-step explanation:

Given,

The ratio of boys to girls in a group is 6:1.

And there are 45 more boys than girls.

To find the number of boys and girls.

Let,

Number of boys = 6x

Number of girls = x

According to the problem,

6x = 45+x

or, 6x - x = 45

or, 5x = 45

or, x = $\frac{45}{5}$

or, x = 9

So,

Number of boys = 6×9 = 54

Number of girls = 9
