Question 237187
1 hour = 60 minutes, therefore:
45 km/hr = 45 km / 60 min
This leads us to 0.75 km/min
Now you need to know how far you traveled in 12 minutes, so:
0.75 km/min * 12 min = 9 km
*** The unit of measure (min) cancels out when you divide min/min, so you're left with unit of measure in km.
Hope this helped!
