Answer:
The unit rate is 85 km per hour.
Explanation:
To find the unit rate you need to find how many units you have if the rate is one.
In other words, if you have travelled 650 km in 8 hours, to find the unit rate you would need to find how many km you could travel for 1 hour.
To find that you need to divide the amount of km travelled by hours travelled. The equation would look like this: 650/8=X. When you divide you get 85 and that is your unit rate, or how many km you travel in one hour.
Hope this makes sense! <3
