Right.
Answered by Damon
Yes, but people in science have a particular approach,
Type the units in such a manner that the ones you do not want cancel

we can use 6 meters / 1 minute
or we can use 1 minute / 6 meters
(both are the same top and bottom, just different units. For this problem one minute IS 6 meters :)

we have
9.6 meters
so
multiply by 1 min/6 meters

9.6 meters (1 min/6 meters)
= 1.6 min

You are welcome.

Damon makes a good point. You know that you can always multiply by 1 without changing anything.

If 6 meters = 1 minute, then

6m/1min = 1
1min/6m = 1

Those "conversion factors" are just different ways of writing 1! If you pick the correct expression, the unwanted units cancel out.

It is particularly helpful if you have a whole string of them.
