Do it in your head.
If you travel at 60 km per hour,
you travel 60 km in 1 hour, so
1 hour is 60 minutes, therefore
you travel 60 km in 60 minutes.
So you travel 10km in 10 minutes!
That's the answer there in red! Doesn't take a lot of knowledge or
calculating. Just requires knowing that there are 60 minutes in
an hour.
