Remember to not round.

Answer:
1.65 km or 33/20 km per minute, 16.5 km or 33/2 km ( for the second question)
Step-by-step explanation:
There's 60 minutes in an hour, so just divide 99 by 60, then you'll get either 1.65 or 99/60 which is simplified to 33/20. And for the second question, multiply the answer from the first question by 10.
