The first step to solving this is figuring out how long each girl took. From there, we can obviously see who took longer!
Let's start with Gabriella, as it's a bit easier to find how long she took.
The problem says that she ran to the rink in 0.4 hours.
Now, what is 0.4 hours in minutes? The easiest way to find that is to:
multiply 60 minutes by 0.4, since 60 minutes is one hour, and we need to find how many of those minutes is in 0.4 hours!
