To find out how far David can travel while skateboarding, we can use the formula:
\[ \text{distance} = \text{speed} \times \text{time} \]
Given:
- Speed = 2.5 m/s
- Time = 100 seconds
Now, substituting the values into the formula:
\[ \text{distance} = 2.5 , \text{m/s} \times 100 , \text{s} \] \[ \text{distance} = 250 , \text{m} \]
The correct answer is:
b) 250 m
