How long is 30 meters?
3 Duoble decker buses
How many double decker buses would i need to carry A million passengers?
Different double-decker buses can carry different numbers of passengers. If all the passengers were to be seated, you would need 13889 London red buses. Of course, a single double-decker bus, over its lifetime, will carry a million (or more) passengers.
Is there way of describing the quantities involved in the news without using number?
In some cases it may be possible by using comparisons, but that depends on the readers being familiar with the concepts. You could say "it fell from the height of a double-decker bus" but that statement would have no meaning to someone who had never seen a double-decker bus. And what would you do if it fell from twice that height? You could not say 2 double-decker buses because that is using a number (2).
In Mr. Decker's class the ratio of boys to girls is 3 to 7. The class sizes at Mr. Decker's school range from 22 to 34 students per class. What is the total number of students in Mr. Decker's class?
3 boys to 7 girls is 3 boys per 10 students gives class size of 13 too small; 6 boys per 20 students gives class size of 26; 9 boys per 30 students gives class size of 39 too many; class size is 26
Does mean mean average?
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
