Question

Someone please help me! :) I need somone to teach me how to work this.

3. A distance-time graph indicates than an object moves 100 m in 4 s and then remains at rest for 6 s. What is the average speed of the object?


50 m/s
25 m/s
10 m/s
100 m/s

Answer 1

I don't want to be given the answer I want someone to help me work it out.

Answer 2

So I can find it on my own :)

Answer 3

well you know s=v*t

Answer 4

so v=s/t

Answer 5

No I don't :(

Answer 6

suppose the object starts moving at t=0..then it moves upto 4s and doesn't move for next 6s....implies total time under consideration is 10s..now use the formula
speed=distance/time=100m/10s=10m/s

Answer 7

whats the speed and difference?

Answer 8

I'm sorry :/ I don't want to bother you but I just really need help :(

Answer 9

Speed is how far something moves in a certain amount of time. For example a car driving 100 kph is going to travel 100 kilometres in 1 hour. So how far has the object in this question moved, and how long has it taken to move that far?

Answer 10

it moved 100 miles in 4 seconds?

Answer 11

m is for meters not miles, so 100 meters in 4 seconds
the other part to this question is that it stops and waits for another 6 seconds
so what is the time in total? its 10 right, so 100 meters in 10 seconds
But the question wants the speed per 1 second not per 10 seconds. So how many meters did it move on average each second?

Answer 12

Could you write this in a equation? Maybe I could understand it better that way.

Answer 13

Its C i took that quiz already lol.
