Answer:
The speed of marble is 1.5 m/s
Step-by-step explanation:
Consider the graph shown below.
As we know:
To find the speed we need to substitute the value of distance and time by using the graph shown below.
From the graph we know when time was 0s marble covers a distance of 0 m.
When time was 2s marble covers a distance of 3 m.
Now substitute the value of distance and time in above formula.
Hence, the speed of marble is 1.5 m/s

The rule of scientifinc notation is that we can use number between 0 and 10, so here we can use 2.8. Lets do this
280 000 000 = 2.8 * 100 * 1 000 000
Now we can just multiply 2.8 by 10 to the power of number of 0 reapeted
So
- its the result
280 000 000 = 2.8 * 100 * 1 000 000
Now we can just multiply 2.8 by 10 to the power of number of 0 reapeted
So
