Question

Carly traveled by bicycle to her favorite local shop. The graph below represents the relationship between distance and time on her bike trip.

Which statement is the BEST analysis of Carly's travels?



Which statement is the BEST analysis of Carly's travels?

Question 3 options:

Carly traveled at a constant speed for 200 s and then accelerated for 50 s. She then traveled at a slow constant rate the remainder of her bike ride.


Carly accelerated throughout the entire bike trip, except for 50 s where she traveled at a constant rate between points C and D.


Carly accelerated for 250 s and then traveled at a constant rate for 50 s. She then accelerated again for the last 100 s.


Carly traveled at a constant speed for 200 s and then increased her speed to a new rate for 50 s. She remained stationary for 50 s and then traveled at a constant speed for 100 s.

Answer 1

the second option is the right answer

Answer 2

Answer:- Last option is the right answer.

Explanations:- We know that,
`speed=(distance)/(time)`

For point A to B, 750 m distance is covered in 200 seconds.

So, speed for A to B point =
`(750m)/(200s)` =
`3.75(m)/(s)`

For point B to C, 500 m distance is covered in 50 seconds.

So, speed for B to c point =
`(500m)/(50s)` =
`10(m)/(s)`

For point C to D, zero distance is covered means Carly is stationary and the bike speed is 0.

For point D to E, 500 m distance is covered in 100 seconds.

So, speed for D to E point =
`(500 m)/(100 s)` =
`5(m)/(s)`

Now, if we look at all the given options then only the last option is correct.

Carly traveled at a constant speed for 200 s and then increased her speed to a new rate for 50 s. She remained stationary for 50 s and then traveled at a constant speed for 100 s.
