Question

motivational speaker writes at a constant rate of 1/2 speech every 3/4 hour. At this rate, what fraction represents the number of speeches the speaker writes per hour?

Answer 1

`x=(2)/(3)(speechs)/(hour)`

Explanation:

we know that

Using proportion

`((1/2))/((3/4))(speechs)/(hours)=(x)/(1)(speechs)/(hour)\\ \\x=((1/2))/((3/4))\\ \\x=(4)/(6) \\ \\x=(2)/(3)(speechs)/(hour)`
