4. Charlie walks in a straight line at a steady speed of 2 m/s for 15 seconds. Work out the distance Charlie traveled from the starting point after 10 seconds of walking.



Answer :

To find the distance Charlie traveled from the starting point after 10 seconds of walking, we can follow these steps:

1. Identify the given information:
- Charlie's walking speed is [tex]\( 2 \)[/tex] meters per second (ms⁻¹).
- The time for which we need to calculate the distance is [tex]\( 10 \)[/tex] seconds.

2. Use the formula for distance:
The formula to calculate distance when speed and time are known is:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]

3. Substitute the given values into the formula:
In this case:
[tex]\[ \text{Speed} = 2 \, \text{meters per second} \][/tex]
[tex]\[ \text{Time} = 10 \, \text{seconds} \][/tex]

4. Perform the multiplication:
[tex]\[ \text{Distance} = 2 \, \text{meters/second} \times 10 \, \text{seconds} = 20 \, \text{meters} \][/tex]

So, the distance that Charlie traveled from the starting point after 10 seconds of walking is [tex]\( 20 \)[/tex] meters.
