Ineed this anwser asap the distance time graph for four objects is shown below: which object is moving at constant speed? object a object b object c object d

Hey !

The anwer is : A.

Because an object is moving at constant speed ( whic is distance/time) when the distance and the time grow directly proportional . (it means when the distance is getting bigger,then the time is getting bigger equally).

The formula for speed is:

Where x is the 'rise' and t is the 'run'. If x is growing faster for every interval of t, it means that the speed is increasing. The only way this can happen is if x has exponential, cubic or quadratic growth.

Because you need constant speed, your answer is the line with the constant slope, or Object A.

the correct choice is a .

do not post any more test or exam questions on

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
