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.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
