Question

A diver ascended 8/9 of a meter in 1/9 of a minute. What was the divers rate of ascent in meters per minute?

Answer 1

The ration between the ascent and time is 8/9 is to 1/9. To get the rate per minute, your aim is to get an equal ratio using a full minute. A full minute would be 9/9. Now how do we get 9//9, you multiply 1/9 by 9.


`(1)/(9)*9 = (9)/(9)=1`

Now to get an equal ration, you need to multiply the ascent by the same factor. So you would multiply 8/9 by 9 as well.


`(8)/(9)*9 = (72)/(9) =8`

So the rate would be 8 meters per minute.
