Answer:
30.9 minutes
Step-by-step explanation:
Note: Depends on how you are being asked to simplify.
5 1/10 and 9 9/10 can both be simplified to 5.1 and 9.9. To find out how long it would take you to go 5.1 km while going 9.9 km/h, you divide 5.1 by 9.9, and you get 0.5151515151... (51 is repeating). We can simplify that to 51.51%. 51.51% of 60 (60 minutes in one hour) is equal to 30.9 minutes.
Note: you should probably do the math based off of the 0.51515151 depending on how the website wants you to simplify.
