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.
