Question

During which time interval was the motion fastest?

A.1 h to 2 h

B.2 h to 3 h

C.3 h to 4 h

D.4 h to 5 h

Answer 1

the answer is D hope this can help youXD

Answer 2

D.4 h to 5 h

Step-by-step explanation:

The velocity of an object is defined as

`v=(d)/(t)`

where

d is the displacement

t is the time

In a displacement-time graph, such as the one in the figure, the velocity of the object corresponds to the slope of the curve. We see that in this graph, the part where the slope is steeper is between 4h and 5h, so this is the moment where the object is moving faster.
