Can someone answer this

Answer:
Step-by-step explanation:
She is riding fastest when the slope is steepest, in this case from 2 to 3 hours.
Answer:
Hours 2 and 3
Step-by-step explanation:
The graph below shows the distance that Janey traveled on a bicycle trip. Between which hours was she riding the fastest?
First, note that speed = distance / time. (for example, a speed of a car could be 3 miles (the distance) per hour (the time))
So, for her to travel the fastest in one hour, the distance traveled in an hour must be the greatest.
Between hours 0 and 1, she traveled 20 - 0 = 20 miles.
Between hours 2 and 3, she traveled 60 - 30 = 30 miles.
Between hours 3 and 4, she traveled 60 - 60 = 0 miles.
Between hours 4 and 5, she traveled 70 - 60 = 0 miles.
So, Janey was traveling the fastest between hours 2 and 3.
