Average speed</u></h2>
Given that each week, Rosario drives to an ice-skating rink that is 60 miles away, and the round-trip takes 2.75 hours, to determine, if she averages 55 miles per hour on his way to the rink, what is her average speed to return to his house, the following calculation must be made:
- 55 = 1
- 60 = X
- 60 / 55 = X
- 1.09 = X
- 2.75 - 1.09 = 1.66
- 55 = 1
- 27.5 = 2
- 55 / 3 x 2 = 36.66
Therefore, Rosario's average speed on her way home is 36.66 miles per hour.

A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.
What is a ratio?
A ratio in mathematics shows how many times one number contains another. For example, if a bowl of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon-to-orange ratio is 6:8, and the orange-to-total fruit ratio is 8:14.
A group of preschoolers has 30 boys and 13 girls.
Total children will be = 30 + 13 = 43
Ratio = number of boys/total children
= 30/43.
Hence, if A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.
