Jessie rode her bike up a 4 km hill then back down. It took her 3 hour

Check your units. Distance should be in kilometer and time should be in hour.

Answer:

8 km per hour or 8 km/hr

Step-by-step explanation:

If riding 4 km took her 1/2 an hour then you multiply by 2 to get 8 km for 1 hr. 8 km for 1 hour means she was going 8 km per hour.
